nonemissive or weekly fluorescent when dissolved in their good solvents but become highly emissive when aggregated in their poor solvents or fabricated into thin solid films, showing unusual phenomena of aggregation-induced (AIE) and -enhanced emissions (AEE). Restriction of intramolecular rotations in the aggregate state is rationalized to be the main cause for the AIE and AEE effects. Photoluminescence (PL)
