二苯并噻咯类化合物的应用研究进展

摘要

Dibenzosilole-based compounds have special organic light emitting properties, as a result of the combination of the orbit characteristics of the main group elements and the rigid coplanar structure, silole ring is located in the center of the structure. These compounds are reported to have high electron affinity and conductivity, facilitate the electron transportation and lower the unoccupied molecular orbital ( LUMO) energy, originating from σ*-π*conjugation between theσ*-antibonding orbital of the exocyclic Si-C bond and theπ*antibonding orbital of the butadiene fragment. Organic light-emitting diodes, solar cell or photovoltaic cell, field effect transistor and explosive substances detection aspects of this kind of compounds were discussed.%二苯并噻咯类化合物，将主族元素硅的特性与其本身的刚性共平面结构相结合，具有特殊的有机电致发光特性。噻咯环位于结构中心，硅原子的两个环外硅原子的两个环外σ*轨道与丁二烯部分的π*轨道产生σ*-π*共轭，可以有效降低最低未占有轨道( LUMO)的能量，提高电子亲和性和导电性，有利于电子的传输，本文着重对该类化合物在有机发光二极管、太阳能电池或光伏电池、有机场效应晶体管及爆炸性物质检测等方面的研究进展。
