the Suzuki coupling reaction. The UV-Vis absorption and fluorescent emission experiment show that all four compounds exhibit obvious aggregation-induced emission (AIE) properties. More importantly, these materials can identify and recognize nitro explosives for the aqueous phase as fluorescent probes. The fluorescent titration results indicate compounds
