| Outline of Final Research Achievements |
Aggregation-induced emission (AIE) dyes, which quench fluorescence in solution and emit strongly in the solid state, have been used in a variety of applications for biomolecular imaging and solid-state luminescent materials. We focused on stilbenes, which are known to undergo large structural changes around their double bonds after irradiation. We designed an aggregation-induced luminescent dye by means of "bridged stilbene" with a alkylene chain around the double bond. We developed the bridged stilbenes BPST[7] and DPB[7], which demonstrate excellent AIE behavior.
