Triarylamine (TAA) derivatives show self-assembly behavior in several organic solvents. Especially, in chlorinated solvents, TAA compounds are oxidized into the radical cation under light irradiation and transformed to nano-rod type self-assembled structures. Interestingly, when TAA derivatives in chlorinated solvent are exposed to circularly polarized light (CPL), chiral self-assembled supramolecules with helicity were obtained. Here, we synthesize the TAA compound with an increased number of aromatic rings at core and induce the chiral self-assembly by irradiation of circularly polarized light (CPL). Chiral self-assembled structure obtained from the core-extended TAA compound is expected to show improved stability much more than the stability of chiral supramoleculs from triphenylamine derivatives. |
