In this study, single crystal structure analysis and charge transport simulation between two neighboring molecules of butyl-substituted phthalocyanine (C4PcH₂) were carried out. As a result of the simulation, high carrier mobility in the column axial direction was calculated, which is a better carrier transport property than that of hexyl substituted phthalocyanine (C6PcH₂). Furthermore, C4PcH₂ thin films were prepared by bar coating method. We investigated the molecular orientation and crystal structure of the films by X-ray diffraction, and fabricated MOSFET devices to evaluate the field-effect mobility.
