Triphenylamine (TPA) derivatives are widely used as photoconductors and charge carriers. Interestingly, triphenylamine containing molecules show self-assembly behavior on light exposure in chlorinated solvent. Previously, we demonstrated the construction of supramolecular polymer with desired handedness by circularly polarized light. Triphenylamine containing molecule with short diacetylene moieties was self-assembled into helical nanostructure in a chlorinated solvent by circularly polarized light, and the chirality could be fixed by photopolymerization of diacetylenes. In this study, triphenylamine containing molecule with longer diacetylene group were synthesized and their self-assembled structure by light was investigated. |
