Subphthalocyanine (SubPc) is a compound with a π-conjugated skeleton, but has been reported to have a non-planar structure, resulting in high values for organic field-effect transistors¹⁾. Previous studies have shown that the introduction of alkyl chains with a large carbon number at the ends of SubPc leads to discotic liquid crystallinity due to the interaction between the side chains^{2, 3)}. In this study, we introduced alkyl thiol groups with different carbon numbers at the ends of SubPc and evaluated the changes in its liquid crystal properties.
