Self-assembly of chiral dye molecules toward CPL active molecular systems

We are developing self-assembling supramolecular polymers of chiral dye molecules to achieve enhanced circularly polarized luminescence (CPL) on the basis of supramolecular chirality.

Circularly polarized luminescence in supramolecular assemblies

Chiral bichromophoric molecules with a twisted structure exhibit highly selective chiral recognition on self-assemlby and co-assembly.

CPL photoswitch

Photoresponsive tetra-thiazole with one-handed helical conformation was employed to tether emissive moieties. Photochromic reaction successfully modulated chiral arrangement and interactions between the emissive moieties to control the CPL activity.
