Disclosed is a novel organic semiconductor material which has a twisted quaterphenylene skeleton as a central unit and simultaneously possesses a skeleton having an electron-transporting property and a skeleton having a hole-transporting property at the terminals of the quaterphenylene skeleton. Specifically, the organic semiconductor material has a [1,1′:2′,1″:2″,1′″]quaterphenyl-4-4′″-diyl group, and one of the terminals of the [1,1′:2′,1″:2″,1′″]quaterphenyl-4-4′″-diyl group is bonded to a skeleton having an electron-transporting property such as a benzoxazole group or an oxadiazole group. A skeleton having a hole-transporting property such as diarylamino group is introduced at the other terminal. This structure allows the formation of a compound having a bipolar property, a high molecular weight, an excellent thermal stability, a large band gap, and high triplet excitation energy.
揭示了一种新颖的有机半导体材料,其具有扭曲的四苯乙烯骨架作为中心单元,并同时在四苯乙烯骨架的末端具有具有电子传输性能的骨架和具有孔传输性能的骨架。具体而言,该有机半导体材料具有[1,1′:2′,1″:2″,1′″]四苯基-4-4′″-二基基团,其中[1,1′:2′,1″:2″,1′″]四苯基-4-4′″-二基基团的一个末端与具有电子传输性能的骨架(如苯并噁唑基团或噁二唑基团)结合。另一个末端引入了具有孔传输性能的骨架,如二芳胺基团。这种结构允许形成具有双极性、高分子量、优异热稳定性、大带隙和高三重激发能量的化合物。
