He graduated from the Department of Physics at the University of Nebraska in 1957 with a bachelor's degree in physics. He received his PhD in physics from the University of California, Berkeley, in 1961. From 1962 to 1982, he worked in the Department of Physics of the University of Pennsylvania, USA, and in 1967 he was appointed as a professor in the Department of Physics of the University of Pennsylvania. In 1982, he became a professor in the Department of Physics at the University of California, Santa Barbara, and served as the director of the Institute of Polymers and Organic Solids established by him at the school. In order to accelerate the industrialization of scientific research results, he co-founded UNIAX in 1990 with P. Smith, a professor in the Department of Materials of the school, and served as chairman and president. He is currently the director of the Institute of Solid Polymers and Organics at the University of California and a professor of physics. He became one of the three winners of the 2000 Nobel Prize in Chemistry for his discovery of conductive polymers. (The other two are: American scientist Alan MacDiarmid and Japanese scientist Hideki Shirakawa). Alan Haig's academic achievements Professor Alan Haig's main pioneering contributions in the fields of physics and materials science research of organic and polymer optoelectronic materials and devices include: 1973 publication of organic charges with metallic conductivity in the TTF-TCNG class The research on transfer complexes pioneered the research on organic metal conductors and organic superconductors; the publication of the doping research on polyacetylene in 1976 created the research field of conductive polymers, which also promoted the development of theoretical research on low-dimensional physics. In 1990, together with Su Wupei and J.R. Schrieffer, he published the SSH model to explain the neutral excitation of polyacetylene. In 1991, he proposed to use soluble ***-yoke polymers to realize high-efficiency polymer light-emitting devices, which opened up the practical development of polymer light-emitting devices. In 1992, he proposed a new concept of ion-induced processability, thus realizing people's dream of developing conductive polymers with both high conductivity and processability for many years, and proposing a new direction for the practical use of conductive polymers; in 1996 The first optically pumped laser in the solid state of a yoke polymer was published. Alan Haig attaches great importance to transforming scientific research results into productivity. In recent years, he has led the research team of UNIAX to solve a series of basic and technical problems such as the high efficiency and long working life of polymer luminescent monochrome displays, making polymer luminescent displays enter the industrialization stage. He attaches great importance to combining basic research with applied research. These enabled him to not only participate in the creation of the research field of conductive polymers, but also for more than 20 years he and the research group he led have always been at the forefront of the research field of conductive polymers and polymer optoelectronic materials. So far, Professor Haig has obtained more than 40 US patents and published 635 papers (statistics as of June 1999). According to the 10-year statistics compiled by SCI from 1980 to 1989, he ranked 64th in terms of the number of citations of his published papers in various research fields. He was the only physicist in the top 100 in the 10-year statistics. Honors Professor Alan Haig has received many awards as an internationally renowned physicist, the most important of which are: the American Physical Society's Oliver E. Buckley Condensed Matter Physics Award in 1983; the Balzan Foundation's New Materials Science Award in 1995 Award; won the Nobel Prize in Chemistry in 2000, etc. In addition, Professor Alan J. Heeger has been awarded honorary doctorates by many universities. Qualitative breakthrough In people's minds, plastic is non-conductive. In ordinary cables, plastic is often used as an insulating layer outside conductive copper wires. However, the achievements of this year's three Nobel Prize winners have challenged people's accustomed concepts. Through research, they found that after special modification, plastic can behave like metal and become conductive. Everyone knows that plastic, unlike metal, is not conductive under normal circumstances.

In real life, people often use plastic as insulation material. Ordinary wires have copper wires in the middle and plastic insulation layers on the outside. But what is surprising is that the person who won this year's Nobel Prize in Chemistry broke this conventional understanding. He discovered that, after certain modifications, plastic could become a conductor. The Royal Swedish Academy of Sciences decided on the 10th to award the 2000 Nobel Prize in Chemistry to American scientists Alan Haig, Alan MacDiarmid and Japanese scientist Hideki Shirakawa for their discoveries about conductive polymers. The so-called polymer is a macromolecular substance formed by the union of simple molecules. Plastic is a kind of polymer. For a polymer to be able to conduct electricity, the carbon atoms within it must be bonded alternately with single and double bonds, and they must be doped—that is, lose or gain electrons through oxidation or reduction reactions. Promoting development Haig, Mark Diarmid and Hideki Shirakawa made some original discoveries in the late 1970s. Due to their pioneering work, conductive polymers became an important field of research for physicists and chemists. , and produce many valuable applications. Using conductive plastic, people have developed computer screensavers that protect users from electromagnetic radiation and smart windows that can remove sunlight. In addition, conductive polymers continue to find new uses in products such as light-emitting diodes, solar cells, and mobile phone display devices. Introduction to the winners: Haig, Mark Diarmid and Hideki Shirakawa. At 15:15 on October 10, 2000 (21:15 Taipei time), the Royal Swedish Academy of Sciences announced that the three Scientists won this year's Nobel Prize in Chemistry for their discovery and development of conductive polymers. They are: Alan J. Haig of the University of California, USA, Alan G. Makdilmi of the University of Pennsylvania, USA, and Hideki Shirakawa of the University of Tsukuba, Japan. Everyone knows that plastic is different from metal. Under normal circumstances, it cannot conduct electricity. In real life, people often use plastic as insulation material. Ordinary wires have copper wires in the middle and plastic insulation layers on the outside. But what is surprising is that the person who won this year's Nobel Prize in Chemistry broke this conventional understanding. He discovered that, after certain modifications, plastic could become a conductor. Plastic is a polymer, and the countless molecules that make up plastic are usually arranged in long chains and repeat this structure regularly. For plastic to be able to conduct electricity, the carbon atoms must alternate between single and double bond binders, and they must be able to allow electrons to be removed or attached, which is commonly known as oxidation and reduction. In this way, these extra electrons can move along the molecules and the plastic can become a conductor. These three scientists first discovered this principle in the late 1970s. Through their efforts, conductor plastics have developed into a scientific field focused on by chemists and physicists. This field has given birth to some very important practical applications. The three of them won the 2000 Nobel Prize in Chemistry for this outstanding contribution. Reasons for the award: Alan Haig is a pioneer in the research field of semiconductor polymers and metal polymers. He currently focuses on semiconductor polymers that can be used as luminescent materials, including photoluminescence, light-emitting diodes, luminescent electrochemical cells, and lasers. wait. Once these products are successfully developed, they will be widely used in many fields such as high-brightness color LCD displays.

Personal Autobiography I was born on the cold morning of January 22, 1936, in Sioux City, Iowa. I spent my childhood in Akron, Iowa, a small Midwestern town of 1,000 people about 35 miles outside of Sioux City. I went to elementary school in Akron. When I was 9 years old, my father passed away. Ellen Hager After my father died, we moved to Omaha so that my mother could be near her family. She raised us alone and we lived in a house with her sister and their children. One of my earliest memories is of my mother telling me the importance of getting a college education. When my mother graduated from high school, she received a scholarship to college, but her parents needed her to help support the family, so she had to work. Before my generation, neither of my parents had received an education beyond a high school degree, so I was always very aware that college was my responsibility. My brother and I were the first in our family to earn PhDs. My high school life was full of fun and frustration, a typical teenage life. The greatest reward of my high school years was meeting my wife, Ruth, whom I have loved for almost 50 years and who remains my best friend. My years at the University of Nebraska were a special time in my life. When I first entered college, my goal was to be an engineer. I had no idea that one could pursue scientific exploration as a career.

But after one semester, I was convinced that I wasn't cut out to be an engineer. When I graduated from college, I majored in physics and mathematics. The most exciting class in college was Modern Physics taught by Theodore Jorgensen. He introduced me to the world of quantum physics and 20th century science. At Berkeley, my initial goal was to do a purely theoretical thesis with Charles Kittel. So I decided to go full-time and get my degree, and I first went to Kittle and asked him if I could work for him. Instead, he suggested that I consider working with people who were doing experimental work that was closely related to theory. This is probably the best advice anyone has ever given me. I followed his advice and joined Alan Portis' research group. I clearly remember my first day in the lab. I was doing "original research" that finally involved real physics. Regarding the magnetic measurement of the insulating antiferromagnet KMnF3, I only did it for one day, and then I wrote a theory of antiferroelectric antiferromagnets and showed it to Portis very proudly. He was patient with me and a few days later I apologized to him and told him my theory made no sense and he was still patient with me. Through my association with Portis, I learned how to think about physics; more importantly, I began to learn good discernment in choosing topics. In 1975, the first articles about a new metal polymer, sulfur-nitrogen polymer (SN)x, appeared in the literature. This unusual quasi-one-dimensional metal piqued my interest and I wanted to join the game. I learned that Professor Alan MacDiarmid from the Department of Chemistry at the University of Pennsylvania had a chemical research background in sulfur-nitrogen polymers, so I made an appointment to meet with him in order to persuade him to cooperate with me in the synthesis of (SN)x. He agreed, and a real collaboration began. We realized that it was a long-term research spanning the two disciplines of chemistry and physics, so we decided to learn from each other. Although we collaborate during working hours during the week, we usually meet on Saturday mornings when we have no other arrangements, just to learn as much as possible from each other. At that time, I was fascinated by the metal-insulator transition theory conceived by Mott. Soon, we discovered for the first time that the electrical conductivity of (CH)x has been significantly improved, and it was confirmed that the increase in electrical conductivity is caused by the transition from insulator (semiconductor) to metal. I loved the life of a scientist and sharing the days of excitement and disappointment with Ruth. She filled my life with love and beauty and graciously tolerated my eccentricities for over 40 years. As a couple, we have successfully built an academic empire, and our two sons, Peter and David, are both engaged in academic research. Peter is a professor, MD, doing research in immunology at Case Western Reserve University. David is a professor and neuroscientist at Stanford University, where he studies human vision. Of all the congratulations I received after winning the Nobel Prize, what pleased me the most was the pride my grandchildren received from their grandfather.

Conductor plastic Alan Haig Alan Haig Conductor plastic can be used in many special environments. Conductor plastic is used in antistatic materials required for photographic film and anti-electromagnetic radiation shields for computer monitors. Some recently developed semiconductor polymers can even be used in light-emitting diodes, solar cells, and displays for mobile phones and mini-TVs. Research on conductor polymers is closely related to the rapid development of molecular electronics. It is estimated that in the future we will be able to produce transistors and other electronic components containing only a single molecule, which will greatly increase the speed of computers and reduce the size of computers. The laptops we carry in our briefcases now may only be the size of a watch by then.
