A process for the implementation of a functional group assisted photochromic solid material

Abstract

The application provides a functional group assisted implementation process of a photochromic solid material, and the prepared porous structure material has characteristics such as high porosity and high specific surface area, and through a liquid phase adsorption loading method, DASAs molecules can be well distributed in a metal-organic framework, and there is sufficient space for isomerization, so that the accumulation between molecules is effectively prevented. The application has the following advantages: (1) the structure stability of the prepared MOFs and the provided free space make the MOFs have a solvent-like property, so that the photochromic characteristics of the DASAs are well exerted. (2) during the loading process, the DASAs are not damaged or water-induced isomerization phenomenon occurs, so that the stability of the DASAs is ensured. (3) by replacing different functional groups, the physical and chemical environment of the MOFs can be adjusted, and the photochromic properties of the DASAs are further optimized.
