Synthesis and Properties of Semiconducting and Metallic Derivatives of Polyacetylene, (CH)x

摘要

Polyacetylene, (CH)x is the simplest organic polymer. Through chemical doping, the electrical conductivity of films of (CH)x can be varied over twelve orders of magnitude with properties ranging from insulator (sigma less than 10 to the minus 10 ohm to the minus 1 cm to the minus 1) to semiconductor to metal (sigma greater than 10 to the 3rd power ohm to the minus 1 cm to the minus 1). Both donors and acceptors can be used with these flexible, free-standing polycrystalline polymer films (thickness 10 to the minus 5 cm to 0.5 cm) to yield n-type or p-type material. In this review, we summarize some of the more important chemical and physical properties of (CH)x and its doped derivatives. (Author)
