Chiral supramolecules with optoelectronic functions are expected to open new opportunities in many fields, but their practical use remains unexplored. I will introduce fabrication of homochiral and heterochiral supramolecular assemblies using chiral organic semiconductors and their structure-property relationships. Owing to the well-ordered packing, homochiral nanomaterials exhibit superior charge transport with significantly higher photoresponsivity and dissymmetry factor, which enables highly selective detection of circularly polarized light. Interestingly, the heterochiral nanostructures assembled from co-self-assembly of racemic mixtures show extraordinary chiral self-discrimination phenomenon. I will also talk about the synthesis of chiral supramolecular biocoordination polymers (SBCPs). Notably, the chiral self-sorted SBCPs exhibit multifunctional properties for various sensors, including photochromic, photoluminescent, photoconductive, and chemiresistive characteristics. |
