Conducting polymers: Halogen doped polyacetylene

A study of the electrical conductivity of the halogen doped transpolyacetylene system, (CH)x, is reported. When films of trans- (CH)x are exposed to chlorine, bromine, or iodine...

Electron spin resonance of polyacetylene and AsF5-doped polyacetylene

The results of an electron spin resonance (ESR) study of trans-polyacetylene, before and after doping with AsF5, are reported. The undoped polymer exhibits a Lorentzian line (g=...

Polyacetylene, (CH)<i>x</i>: <i>n</i>-type and <i>p</i>-type doping and compensation

A series of experiments are reported which demonstrate that donors or acceptors can dope polyacetylene to n type or p type, respectively, and that the two kinds of dopants can c...
