| Outline of Final Research Achievements |
Highly luminescent materials are of great interest for use in light-emitting devices. However, the luminescence intensity of most organic molecules is abruptly reduced in condensed phases owing to aggregation-caused quenching. Recently, some types of organic molecules have shown strong photoluminescence in the condensed phase, where aggregation enhanced the photoluminescence through a phenomenon called aggregation-induced emission (AIE). The structure of their molecular aggregates, as well as their own molecular structure, must strongly affect the luminescence of AIE materials. We have developed liquid-crystalline (LC) luminophores with the AIE property (AIEgen). We observed that acrylate polymers having an LC AIEgen in their side chain changed the luminescent color from blue to white by the glassy-to-LC phase transition.
