Preparation method of pyrazolone/fluorescent dye self-assembling heterostructure material

Abstract

The invention provides a simple preparation method of a pyrazolone / fluorescent dye self-assembling heterostructure material. According to the preparation method, the pyrazolone photochromic material 1, 3-diphenyl-4-(3-chlorobenzene methylene)-5-pyrazolone semiphenyl semi carbazide (DP3ClBP-PSC) which is stable in color changing performance and high in fatigue resistance is adopted as a color change unit in the heterostructure, and is subject to self-assembly with the fluorescent dye 1, 3, 5-triphenyl pyrazoline (TPP) which is high in optical waveguide performance so as to obtain the heterostructure material; and a fluorescence signal of the fluorescent dye is modulated, thus achieving the purpose of fluorescent switching can be achieved. According to the preparation method provided by the invention, a solution synthesis is carried out, and the fluorescent dye is added in the last synthesis process of the pyrazolone photochromic material 1, 3-diphenyl-4-(3-chlorobenzene methylene)-5-pyrazolone semiphenyl semi carbazide (DP3ClBP-PSC) so as to obtain the pyrazolone / fluorescent dye self-assembling heterostructure material; and the fluorescent signal of the fluorescent material is modulated through the pyrazolone photochromic pyrazolone system; and the preparation method is simple in operation, and the cost of fluorescent material is greatly reduced, and the preparation method is easily applied to industrial production.

Description

technical field [0001] The invention relates to a simple preparation method of pyrazolone / fluorescent dye self-assembled heterogeneous structure material. Background technique [0002] Heterostructure materials are a new class of multifunctional materials prepared by simple self-assembly methods, which have potential applications in high-density optical information storage and non-destructive readout devices, holographic anti-counterfeiting, nonlinear optical devices, etc. The design and preparation of photochromic materials and fluorescent materials into heterostructure materials has been widely studied by domestic and foreign scientists. This kind of materials makes up for the shortcomings of photochromic materials with weak fluorescent signals and small signal contrast— The information stored in photochromic materials cannot be accurately and non-destructively read, and cannot meet the technical requirements for fluorescent non-destructive readout. Therefore, the design ...
