Functional dyes are widely used in optical recording, lighting display, biological imaging, medical diagnosis and treatment. It is still an important challenge to expand the luminescent properties and function regulation of fine chemical organic functional dyes, reduce the cost of material synthesis, and improve the economy of molecular material construction process. The construction strategy of "assembling-induced emission" is proposed to effectively regulate the fluorescence emission wavelength and room temperature phosphorescence efficiency of functional dyes and build functional and intelligent organic room temperature phosphorescence materials and product systems, which effectively expands the new functions and applications of traditional organic functional dye.
