N3-PyTPE

TPE-Py-N3,TPE-PyN3,Aggregation induced emission(AlE)is a non luminescent biomolecule that exists in the form of a single molecule in solution.As the solvent gradually evaporates,the fluorescence gradually increases.Tetrastyrene is an important class of aggregated luminescent fluorescent dyes.When the tetrastyrene molecule is in an aggregated or solid state,the rotation within the molecule is restricted.Non radiative channel forbidden excited molecules emit photons back to the ground state.
