1. The directional control of electron flows in photo-induced electron transfer reactions is known to occur across a rectifying junction of inorganic semiconductors. We have succeeded in the observation of rectifying photoredox current on a junction of two polyethylenimine films, one consisting of merocyanine dyes and the other anthraquinone. The polymer bilayer film could easily be prepared by a spin-coating technique.2. From detailed comparison of the photocurrent observed on the polymer-merocyanine film containing a series of quinones with varying redox potentials, it was suggested that the photoinduced electron transfer rate in this polymer film system could be explicable by the "inverted region" of electron transfer theory.3. The self-exchange rate of electrons was investigated by a potential step method using a polymer film consisting of N-methylphenothiazine as a redox species. The result suggested that the nature of polymer matrices has a large effect on the electron transfer process.

1。已知在光诱导的电子转移反应中电子流的定向控制发生在无机半导体的整流连接中。我们成功地观察了在两种聚乙胺膜的连接处纠正光电氧电流，一种由一种由蛋白苷染料和另一种蒽醌组成。聚合物双层膜可以通过旋涂技术很容易制备。2。从在包含一系列具有不同氧化还原电势的奎因酮的聚合物 - 生氨基膜上观察到的光电流的详细比较，提出，该聚合物膜系统中的光诱导的电子传递速率可以通过电子传递理论的“倒置区域”。使用由N-甲基苯噻嗪作为氧化还原物种组成的聚合物膜通过潜在的步骤方法研究了电子的自我交换速率。结果表明，聚合物矩阵的性质对电子传输过程有很大影响。
