Triarylamine (TAA) derivatives show self-assembly phenomenon in several organic solvents. Especially, in chlorinated solvents, TAA compounds are oxidized into the radical cations under light irradiation and transformed to nano-rod type self-assembled structures. Interestingly, when TAA derivatives in chlorinated solvent were exposed to circularly polarized light (CPL), chiral self-assembled supramolecular structures with controlled helicity were obtained. Here, we report the synthesis of the core-extended TAA compounds with an increased number of phenyl rings at core and their 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 compared to the chiral supramoleculs obtained from triphenylamine derivatives having three aromatic rings.
