There are provided a novel compound having a good field mobility, a method of producing of the compound, an organic semiconductor material containing the novel compound, and an organic semiconductor device. The novel compound which is represented by the following general formula (1), (2), (3) or (4) (where Z represents a sulfur atom or a selenium atom, and R represents a hydrogen atom, an alkyl group or a phenyl group in general formulae) has a structure having two benzene rings of naphthalene bonded with a thiophene ring and a selenophene ring, respectively. These compounds have a conjugate system in molecules due to an interaction between π orbitals, and show a strong molecular interaction through a sulfur atom or a selenium atom contained in a thiophene ring or a selenophene ring in each molecule, thereby having a good field mobility.
本文提供了一种具有良好场迁移率的新型化合物、一种生产该化合物的方法、一种含有该新型化合物的有机半导体材料以及一种有机半导体器件。由以下通式(1)、(2)、(3)或(4)表示的新型化合物(通式中 Z 代表硫原子或硒原子,R 代表氢原子、烷基或苯基)具有两个萘苯环分别与一个噻吩环和一个硒吩环键合的结构。由于 π 轨道之间的相互作用,这些化合物在分子中形成共轭体系,并通过每个分子中的噻吩环或 硒吩环所含的一个硫原子或一个硒原子显示出强烈的分子相互作用,从而具有良好的场迁移率。

naphthodithiophenes (NDTs) being potential as new core structures for organic semiconductors is described. The newly established synthetic procedure involves two important steps; one is the chemoselective Sonogashira coupling reaction on the trifluoromethanesulfonyloxy site over the bromine site enabling selective formation of o-bromoethynylbenzene substructures on the naphthalene core, and the other is a facile ring
