The name refers to its conceptual construction from polymerization of acetylene to give a chain with repeating olefin groups .. polymerization. polymerization. acetylene. acetylene. olefin. Olefin fiber. This compound is conceptually important as the discovery of polyacetylene and its high conductivity upon doping helped to launch the field of organic conductive polymers .. conductivity. Ionic conductivity. doping. Doping ( semiconductor ). conductive polymers. conductive polymers. The high electrical conductivity discovered by Hideki Shirakawa , Alan Heeger , and Alan MacDiarmid for this polymer led to intense interest in the use of organic compounds in microelectronics -LRB- organic semiconductors -RRB- .. conductivity. Ionic conductivity. Hideki Shirakawa. Hideki Shirakawa. Alan Heeger. Alan Heeger. Alan MacDiarmid. Alan MacDiarmid. microelectronics. microelectronics. This discovery was recognized by the Nobel Prize in Chemistry in 2000 .. Nobel Prize in Chemistry. Nobel Prize in Chemistry. Early work in the field of polyacetylene research was aimed at using doped polymers as easily processable and lightweight `` plastic metals . ''. Despite the promise of this polymer in the field of conductive polymers , many of its properties such as instability to air and difficulty with processing have led to avoidance in commercial applications .. conductive polymers. conductive polymers. Compounds called polyacetylenes also occur in nature , although in this context the term refers to polyynes , compounds containing multiple acetylene groups -LRB- `` poly '' meaning many -RRB- , rather than to chains of olefin groups -LRB- `` poly '' meaning polymerization of -RRB- .. polymerization. polymerization. acetylene. acetylene. olefin.
