含Silole共轭聚合物的光电性能

Silole是一类含硅杂环戊二烯,近年来,由于其独特的结构特性、分子的可设计性及多样性,在光电领域得到越来越多研究者们的关注。某些silole小分子在有机发光二极管中用作发光层和电子传输层有出色的表现,但近来对含silole聚合物的研究也颇受重视,在聚集态诱导发光、化学传感器、聚合物发光二极管、聚合物太阳能电池、场效应晶体管中的应用相继有报道。因此silole是一类很有潜力的构筑光电功能材料的杂环化合物。本文根据其母体结构的不同对含silole的聚合物光电性能研究进展进行了综述。

Optoelectronic Properties of Silole-Containing Polymers

Siloles are a group of five-membered silacyclics,which have drawn much attention due to its unique electronic structures,molecule diversity and designability recently.High performance OLED can be made using small silole molecules as emitting materials or electron transfer materials.Silole-containing polymers have also attracted much attention of a number of chemists.Besides the high conductivity,many new properties have been found,such as highly efficient power conversion efficiency in plastic solar cells,fast carrier mobility in field-effect transistors(FET),high efficiency in polymeric light-emitting diodes(PLEDs),etc.Thus siloles are promising optoelectronic functional materials.In this review,the optoelectronic properties of silole-containing polymers are described according to the different structures of their parent compounds.
