The present invention provides thiophene derivatives (and a polymer thereof) of the following formula, which will respond to light and electricity and which are best suited for use as photorecording materials and light-electricity conversion elements:
(Where n and m are independent integral numbers greater than 0; R₁ is a hydrogen atom, a halogen atom or a trialkylsilyl group; R₂ are an alkylene group which may possess a substitutent group to form a ring with an ethylenic linkage and a -COOCO- group, respectively, or exclusively a cyno group; and R₃, R₄ and R₅ are a hydrogen atom or an alkyl group, respectively.)
本发明提供了下式的
噻吩衍
生物(及其聚合物),它们对光和电都有反应,最适合用作光记录材料和光电转换元件:
(其中 n 和 m 是大于 0 的独立整数;R₁ 是氢原子、卤素原子或三烷基
硅基;R₂ 是亚烷基,可分别具有一个取代基以形成具有
乙烯基连接的环和一个 -COOCO- 基团,或完全是一个炔基;R₃、R₄ 和 R₅ 分别是氢原子或烷基)。
