Structure and geometry influence excited state fluorescence dynamics in aggregation-induced emission molecules

"in both liquid and solid states... aggregation-induced emission where molecules emit light more efficiently as solid/ aggregate, restricting bending, forcing molecule to maintain stable structure emitting light due to quenching effects, restricting access to conical intersection... demonstrated in α-substituted dibenzoylmethanatoboron difluoride... shape changes within few trillionths of second... OLED, bioimaging"
