抄録	Binary blends of phthalocyanine (Pc) LCs, 1, 4, 8, 11, 15, 18, 22, 25-octadecylphthalocyanine (C10PcH2) and the corresponding Zn complex (C10PcZn) were studied which have the identical hexagonal columnar (Colh) mesophase and the same order of carrier mobility (~ 10-1 cm2 V-1 s-1) in the mesophase. The phase diagram shows a complete miscibility in the Colh mesophase and no eutectic point was detected. The carrier mobility evaluated by Time-Of-flight (TOF) technique goes down to 10-2 cm2 V-1 s-1 in Colh phase of the initial blends prepared by solution mixing. However, the treatment of these binary systems with repetitive heating and cooling gives recovering of carrier mobility to the original level, though their HOMO and LUMO levels are slightly different in these two mesogenic Pcs. These results indicate that two types of single component column form a hexagonal array in mesophase. Also the blends with PCBM were studied on carrier mobility as well as miscibility and phase separation.
