Hemiphasmidic mesogen units are composed of two parts with different shapes, a rod-like and a half-disc moieties that are linked together.1 Due to the special shape matching mechanism, side-chain liquid crystalline polymers (SCLSPs) with hemiphasmidic mesogen units as the side groups have fantastic ability of self-assembly and can organize into different nanostructures depending on the structures of side groups.
