Organic metals: conducting complexes of poly(2,5-thienylene sulphide) and poly(2,5-thienylene selenide)

Abstract

Exposure of highly purified samples of the new polymers poly(2,5-thienylene selenide)(PTSe) and poly(2,5-thienylene sulphide)(PTS) to arsenic pentafluoride afforded a conducting complex (0.12 S/cm) from PTSe but only a moderately conducting complex(ca. 10^–5 S/cm) from PTS, a result which is in direct contrast to the behaviour of poly(p-phenylene selenide) and poly(p-phenylene sulphide) upon similar treatment.
