2b01 Thermal phase transitions and carrier transport properties of the liquid crystalline phthalocyanine blend/PCBM system

Abstract

The spontaneous formation of bulk heterojunction active layer was studied for the blends of two types of liquid crystalline phthalocyanines as p-type semiconductor and PCBM as n-type one. The blends are the mixtures of the decyl homologue of non-peripheral (np)-phthalocyanine mesogen and the corresponding Zn complex, both of which show the comparable carrier mobility (〜10^<-1> cm^2 V^<-1> s^<-1>) in the Col h mesophase. The thermal phase transition property was clarified for the blends and the drift mobility of charged carriers were measured by TOF method. The correlation between the morphology of blends and carrier transport property was discussed.
