Fabrication of single crystalline thin films utilizing an organic semiconductor material, alkyl-substituted phthalocyanine, which demonstrates a high ambipolar mobility and is promising as a donor material for organic solar cells, has been carried out. The fabrication methods have been proposed by taking the thermotropic LC properties, lyotropic LC properties or crystal polymorphism into consideration, the optical and electrical properties of the single crystalline thin film have been investigated, and the crystal growth mechanisms have been discussed.
