Small organic molecules Glow in the dark materials introduced

Small organic molecules Glow in the dark materials variety, with their multiple and various heterocyclic conjugated chromophore structure is easy to adjust,Glow in the dark materials by introducing ethylenic, benzene and other unsaturated groups and various chromophores to change its conjugate length, so that the compound optical properties change. And as oxadiazole derivatives, triazole and its derivatives, rhodamine and its derivatives, coumarin derivatives, derivatives of 1,8-naphthalimide,glow in the dark pigments pyrazoline derivatives , triphenyl amine derivatives, porphyrin-based compounds, carbazole, pyrazine, thiazole derivatives, perylene derivatives. They are widely used in optical electronic devices, DNA diagnostics, photochemical sensor, dyes, fluorescent brighteners, fluorescent paint, dye laser [7], an organic electroluminescent device (ELD), etc.. However, small-molecule light-emitting materials prone to the phenomenon of fluorescence quenching in the solid state,glow pigments the general method of doping device made ??and easy to gather crystals, down device lifetime. So many researchers working on the one hand, small molecules, on the other hand looking for better performance light-emitting materials, polymer light-emitting material came into being.
