Homochirality is one of the most universal and intriguing phenomena owing to its presence in nature at all length scales from atomic to galaxy level. Among these various levels, homochirality at a supramolecular level has received significant attentions due to its relation to biological molecular self-assembly. Here, we report the formation of homochiral supramolecular domains from self-assembly of achiral triarylamine compounds having extended π-conjugation structures. The triarylamine compounds were designed to have extended π-conjugation cores to induce π- π interactions for self-assembled structures. Interestingly, when the benzene solution of triarylamine compounds was casted in quartz dishes to make solid thin film, the self-assembled supramolecular materials showed optical activity by irradtion of circularly polarized light. |
