Description

Technical field [0001] The present invention belongs to the field of high molecular luminescence hydrogel, and more particularly to a fluorescent molecular monomer and a preparation method thereof, aggregated inducing luminescent hydrogel and preparation method thereof. Background technique [0002] High molecular hydrogel refers to physical effects by hydrophilic polymer chains (such as hydrogen bonds, electrostatic, hydrophilic, ion bonds, crystallization, etc.) or chemical (covalent bonds or dynamic covalent bonds, such as acyl) Key, imine, boroborary bond, etc.) crosslinking to form a three-dimensional network structure, and swelling a large amount of water filling a flexible material in a mesh structure. Hydrogel can absorb a large amount of water in its three-dimensional network structure, swell but do not dissolve, its unique physical chemical properties (such as viscoelasticity, biocompatibility, moisture, etc.) and extensive function plasticity are widely concerned.
