中文摘要：

有分隔符组被 Sonogashira 跨 coupling 反应准备的沸或唑的包含卟啉的结合的聚合物。聚合物在沸上分子量高或唑单位在普通有机溶剂使结合的聚合物可溶，例如 THF 和甲又氯化物。聚合物能从答案扔形成高质量的持久的电影。他们的光并且光电流应答的性质被调查。光电流反应与卟啉的内容直接成正比，这被发现。进聚合物链的唑单位的加入也在某程度把积极贡献给了光电流产生。

英文摘要：

Porphyrin-containing conjugated polymers with fluorene or carbazole as spacer groups were prepared by Sonogashira crosscoupling reactions. The polymers were of high molecular weight and the flexible alkyl chains on fluorene or carbazole units made the conjugated polymers soluble in common organic solvents, such as THF and methylene chloride. The polymers could form high quality durable films from solution casting. Their optical and photocurrent responsive properties were investigated It was found that the photocurrent response was directly proportional to the content of porphyrin. The incorporation of carbazole units into the polymer chains also gave positive contribution to the photocurrent generation in some extent.
