molecules consisting of oligo(phenylene vinylene) (OPV) asymmetrically end-substituted with a hydrophilic poly(ethyleneglycol) (PEG) segment and a hydrophobic alkyl chain. This amphiphilic structure induces self-assembly into both thermotropic and lyotropic lamellar liquid crystalline (LC) phases. The molecules form strongly fluorescent, self-supporting gels in both water and polar organic solvents

An liquid crystalline organic semiconductor material practical as an organic semiconductor is provided. The material is a liquid crystal composition having a smectic liquid crystal phase. The liquid crystalline organic semiconductor material has a distyrylbenzene structure of formula (1). When heated to a temperature range for the smectic liquid crystal phase followed by being cooled, the material takes on a solid state as a result of phase transition from the smectic phase.
