Transport and Optical Properties of Polythiazyl Bromides.
Abstract
Polymeric sulfur nitride, polythiazyl, (SN)x, has been of interest in recent years as the first example of a covalent polymer which is a metal. Studies of the optical and electronic properties have indicated metallic behavior along the (SN)x chains with sufficient interchain coupling to give the properties of an anisotropic three dimensional metal. As part of a continuing study of the properties of (SN)x we have been investigating its reactions with halogens. In 1969 Patton made brief reference to the fact that (SN)x reacts with chlorine to give NSCl. Bernard et al. have reported recently that (SN)x reacts with bromine vapor at room temperature to give a gray-blue solid the composition of which was not determined. Independent studies carried out by us and by Street et al. involved the characterization of crystals and films of (SNBr0.4)x, the first derivative of (SN)x. In this paper we report the initial results of studies of the electrical transport and optical properties of (SNBr0.4)x and the related derivative (SNBr0.25)x.
