摘　　要： 　合成了一种新型的空穴传输材料三苯胺二苯乙烯衍生物DPAVBi,并通过一系列手段对其进行了表征。DPAVBi具有较好的无定形成膜性及较高的热稳定性。以DPAVBi为电荷传输层,TiOPc为光生层制备的双层光电导体,其光敏性在762nm处达到1.67cm2·μJ-1,是一种优良的空穴传输材料。 A triphenylamine substituted stilbene derivative of 4,4'-bis-[2-[4-(N, N-diphenylamine) -phenyl-1-yl]-vinyl-1-yl]-1',1-biphenyl (DPAVBi) was synthesized. The compound was characterized by a series of ways. The photosensitivity of the dual-layer photoreceptor containing TiOPC as charge generation layer and DPAVBi as charge transport layer was higher than that containing NiN-diethyl-4-amino-benzaldehyde-N, N-diphenyl-hydrazone (DEH) as charge transport layer. For instance, the photosensitivity from DPAVBi was 1.67 cm2·μJ-1 at 762 nm, 2 times higher than that from DEH. DPAVBi also showed amorphous film-forming nature and good thermal stability, promising as a new candidate for hole-transporting materials.
