TPE-COOH

Aggregation induced emission (AIE) is a phenomenon discovered by academician Tang benzhong team in 2001.It is a kind of non luminescent thiazole derivative in the form of single molecule in solution.With the gradual evaporation of solvent,the fluorescence gradually increases.Tetrastyrene is a kind of important aggregation fluorescent dyes.When tetraphenylene is in the aggregated state or in the solid state,the intramolecular rotation is limited and the non radiative channel is blocked,and the excited molecules return to the ground state by emitting photons. Tetraphenylene(TPE)is an outstanding member of AIE system because of its easy modification and high luminous efficiency.Design and prepare two kinds of four-phase silicon-based materials.
