With selenophene as starting material, three selenophene-based organic semiconductor materials, namely, 1,2-bis(5-((E)-4-octylstyryl)selenophen-2-yl)ethene (1), 5,5′-bis((E)-4-octylstyryl)-2,2′-biselenophene (2), and 2,5-bis((E)-4-octylstyryl) selenopheno[3,2-b]selenophene (3), were synthesized. In 1 and 2, two selenophene rings were connected by double and single bonds, respectively, and in 3, two
以硒烯为起始原料的三种硒烯基有机半导体材料,即1,2-双(5-(((E)-4-辛基苯乙烯基)硒代吩-2-基)乙烯(1),5,5'-bis合成了((E)-4-辛基苯乙烯基)-2,2'-苯并芴二烯(2)和2,5-双((E)-4-辛基苯乙烯基)硒烯[3,2- b ]硒烯(3)。 。在1和2中,两个硒烯环分别通过双键和单键连接,而在3中,两个硒烯环稠合在一起。化合物1 - 3表现出良好的结晶性,并显示出p迁移率分别高达0.01、0.11和0.38 cm 2 V -1 s -1的通道特性。这项研究表明,硒烯环的结合方式显着影响了有机场效应晶体管的性能。
