Preparation Of Gel Under Assembly System And Its Application In Quantum Dots Circularly Polarized Light

As an important research field in supramolecular chemistry,organic gels have been widely used in intelligent phase change materials,biomedical materials,assembly nanomaterials,wastewater treatment and chiral luminescent materials.With the rapid development of industry and the development of high-end science and technology,on the one hand,the comprehensive treatment of industrial wastewater has become an important part of environmental protection,on the other hand,chiral luminescent materials have become 3D stereo imaging technology.Optical data storage and encryption are popular research fields.The aim of this paper is to induce chiral luminescence(circular polarized light)of quantum dots by using chiral gels and to prepare two-component organic compounds.Gel is used as adsorbent for wastewater treatment and its adsorption property to dyes is studied.The chiral luminescence of quantum dots was induced by using the gel factor of chiral glutamic acid derivatives as chiral source and inorganic non-chiral quantum dots as luminescent bodies.The chiral transfer between the gel factors and quantum dots was realized by co-assembly.The results show that the chiral transfer between the gel factor and the quantum dot is related to the coassembly of the two factors and the length of the carbon chain between the chiral gel factor and the quantum dot.At the same time,it has been proved that the chiral luminescence of quantum dots induced by co-assembly of gel factor and quantum dots can be achieved for different kinds of quantum dots,and white circular polarized light is successfully prepared for the first time.To prove that by chiral gels,The opon-induced chiral luminescence of quantum dots is a universal method to induce circular polarized light of quantum dots.The gelling properties of N-(4-aminobenzoyl)-L-glutamic acid diethyl ester and polyacrylic acid in 20 different organic solvents and mixed solvents of ethanol and water were studied.It was found that N-(4-aminobenzoyl)-L-glutamic acid diethyl ester and polyacrylic acid could form a stable gel in benzene and toluene solvent,and a stable gel could also be formed in the mixed solvent of ethanol and water.The mechanism of gum formation was preliminarily verified,and the adsorption properties of two-componentorganic gels were tested.It was found that the gel was homogenous to Congo red and methylene blue dyes.It was found that the two-component gel composed of N-(4-aminobenzoyl)-L-glutamic acid diethyl ester and polyacrylic acid had good reproducibility.This provides a potential application of gel in the treatment of water pollution.
