‘Organic metals.’ Synthesis of a new type of organic metal derived from polyacetylene, (CH)x

Abstract

When ca. 85%cis films of the semiconducting polymer, polyacetylene, (CH)_x, are doped with bromine to compositions such as [CHBr_y]_x(y=ca. 0·15–0·35) and then partly dehydrobrominated at 150°C, they yield new semi-conducting polymers such as [CH_0·85Br_0·11]_x which can then be doped with I₂ or AsF₅ to yield new highly conducting organic metals such as [CH_0·89Br_0·09I_0·12]_x and [CH_0·82Br_0·13(AsF₅)_0·12]_x, respectively.
