Abstract

The invention relates to the technical field of sequence color luminescence, in particular to fluorescent organic matter, a fluorescent dye and a sequence color luminescence regulation method. A nitrogen-containing aromatic ring derivative is used as a central group, an aromatic ring is used as a peripheral group, and the central group and the peripheral group are connected through a flexible chain. The preparation process is conducted in an absolute ethyl alcohol solution. The preparation method comprises the following steps: carrying out chalcone condensation reaction on 9-alkyl-carbazole-3,6-dicarboxaldehyde and acetylpyrene under the catalysis of a sodium hydroxide solution with the concentration of 40%, conducting recrystallizing in absolute ethyl alcohol, and conducting cooling and filtering to obtain a powdery sample. The invention also provides a fluorescent dye which is prepared by taking the fluorescent organic matter as a raw material and physically doping PMMA in the fluorescent organic matter, and on the basis, the invention also relates to a method for carrying out sequence color luminescence regulation and control by the fluorescent dye, and the method is convenient for realizing sequence color regulation and control and has very remarkable popularization significance.

Description

technical field [0001] The invention relates to the technical field of sequential color luminescence, in particular to a fluorescent organic substance, a fluorescent dye and a method for regulating and controlling the sequential color luminescence. Background technique [0002] Luminous intensity and luminous color are two important characteristics of light, and humans have done a lot of research on colorful luminescent materials. At present, strategies to obtain fluorescent color regulation include: regulating the size of carbon quantum dots, controlling the type and ratio of halogens in the organic-inorganic hybrid perovskite structure, changing the substituents in organic molecules, and so on. Among them, organic molecules have the characteristics of rich raw material sources and easy structure modification, and have become an important branch of fluorescent dye research and commercialization. It is a common strategy to obtain different fluorescent colors by changing the...
