This paper describes the synthesis and physical study of several new photorefractive polymers. The Heck reaction was successfully applied in the synthesis of these multifunctional polymers. These polymers are conjugated poly(phenylenevinylene)s copolymerized with a small amount of macrocyclic zinc complexes as the photosensitizers. Nonlinear optical chromophores were incorporated as the pendant groups
本文介绍了几种新型光折变聚合物的合成和物理研究。Heck反应已成功应用于这些多功能聚合物的合成中。这些聚合物是与少量作为光敏剂的大环
锌配合物共聚的共轭聚(亚苯基亚
乙烯基)。非线性光学发色团被并入作为侧基。合成了富电子和缺电子的PPV主链。实验结果表明,当使用富含电子的光敏剂时,用于电荷传输的缺电子组分(CN-PPV)增强了光折光性能并缩短了响应时间。
