A supermolecular light-emitting gel system constructed by sulfonated cyclodextrin-bromophenyl picolinate-amino clay and a preparation method thereof are disclosed, wherein the sulfonated cyclodextrin is used as a main body, bromomethyl phenylpyridinate is used as an object, and bromophenyl picoline based on electrostatic interaction and main-object interaction is utilized to successfully construct a novel supermolecular xerogel in which SCD and amino clay are combined in a non-covalent manner. The xerogel network has a rigid structure, can effectively fix the fluorescent powder, limit vibration dissipation and enable the xerogel to emit RTP. In the system, SCD plays a crucial role in maintaining the emission behavior of the monomer, AC provides a layered environment for PYCl through the strong inhibition of the electrostatic gel network structure to the vibration of the fluorescent powder and the radiationless relaxation process, and the supermolecular xerogel can generate a strong RTP signal. In addition, the xerogel has certain responsiveness to humidity, and has potential application prospect in the aspects of organic luminescent materials and humidity sensing. |
