摘要：

The hole transport characteristics of molecule blends of 1,4,5,8,9 and 11-hexaazatriphenylene-hexacarbonitrile(HAT-CN):N,N’-di(naphthalene-l-yl)-N,N’-diphenyl-benzidine(NPB) and HAT-CN:4,4’-cyclohexyhdenebis[N,Nbis(4-methylphenyl)benzenamine](TAPC) with various NPB and TAPC mixing concentrations(5-90 wt%) are studied.When the concentration is in the range of 5-80 wt%,it is found that the hole conductions in the two blends are space-charge-limited current(SCLC) with free trap distributions.The current-voltage characteristics of the two blends show SCLC with exponential trap distributions at the concentration of 90wt%.The hole mobilities of the two blends are very close(10-4~10-3cnr~2V-1s-1),the dependence of electric field and temperature can be described by the modified Poole—Prcnkel model.The hole mobility and activation energy of the two blends depending on concentration are similar.
