Abstract

Detailed experimental evidence is presented showing that the electrically conductive 'poly(carbon diselenide)' synthesized via the pressurization of liquid carbon diselenide at 5000 atm and 100°C consists of an amorphous CSe polymeric material and trigonal selenium. The trigonal selenium consists of a mixture of a microcrystalline and an aggregated polycrystalline phase. The microcrystalline component shows dramatically different melting and crystallization behavior compared with normal polycrystalline trigonal selenium. The metallic conductivity of the material (θRT ≈ 10 S cm-1 and θRT8K ≈ 2.5) is percolation-limited and is probbly associated with the] amorphous CSe polymer.
