A series of π-conjugated 3,10-dialkyl-dinaphtho[1,2-b:2',1'-d]chalcogenophenes incorporating S, Se, and Te as the central chalcogen atom was newly synthesized, and their optoelectronic and charge-transport properties were systematically investigated. High carrier mobilities of up to 4.7 cm V s were achieved for solution-processed organic field-effect transistors using these materials as p-channel organic semiconductors.
新合成了一系列以S、Se和Te作为中心硫族原子的π共轭3,10-二烷基-二萘并[1,2-b:2',1'-d]硫族吩，并对其光电和电荷传输特性进行了系统研究。使用这些材料作为p沟道有机半导体的溶液处理有机场效应晶体管实现了高达4.7 cm² V⁻¹ s⁻¹的高载流子迁移率。
