The mesogenic phthalocyanine, C6PcH₂, is a promising organic material with a high hole mobility of 1.4 cm²V^-2s^-1. It tends to form a columnar structure and is processable in solution. The solution processed thin-film of C6PcH₂ has a polycrystalline structure orienting in random directions, however, a molecular-aligned thin-film must be appropriate for realizing high performance devices. This work reports a method to control the alignment of C6PcH₂ by applying the principle of crystal growth.
