Abstract
In order to reduce the band gap of polydiacetylene, a new class of pol ydiacetylene derivative having sulfur atom directly bound to the main chain was synthesized. The solid state polymerization of the new diace tylenes occurs in the manner of the topochemical and topotactic 1,4-ad dition reaction. The evidence of the electron donating effect of the s ulfur atoms of the polydiacetylenes is obvious in the red shift of the absorption maximum and the asymmetrical bond length alternation of th e main chain.
