The reaction of hf with polyacetylene

Abstract

Anhydrous HF reacts with polyacetylene to produce a material with high conductivity. Infrared spectra of lightly doped samples show bands characteristic of a delocalized positive charge along the polymer chain. Upon heavier doping, conductivities of 1{subset with multiplication sign below}-10 (ohm-cm)-1 are measured. Addition of ammonia produces an ammonium ion on the chain, and destroys the conductivity of the material. A discussion of the doping mechanism and related reactions is given. © 1982 AIME.
