Synthesis and Properties of Halogen Derivatives of (SN)x and (CH)x.

Abstract

Metallic polymeric sulfur nitride may be halogenated at room temperature to give a series of highly conducting polymers which are also metals. Compositions such as (SNBr0.25)x, (SNBr0.4)x and (SNBr0.55)x may be obtained under varying conditions. The conductivity of (SNBr0.4)x is ten times greater than that of (SN)x itself. Crystalline silvery films of the flexible semiconducting polymer, trans 'polyacetylene', take up halogens with enhanced optical and electrical properties. (CHBr0.05)x and (CHI0.22)x have four and seven orders of magnitude greater room temperature conductivities respectively, than trans-(CH)x.
