Abstract

The invention provides a ternary rare earth complex and application of the complex in preparing high-strength hybrid luminous hydrogel. The chemical structural formula of the ternary rare earth complex is shown as follows. First terpyridyl bridged imidazolium salt is used for being combined with a rare earth beta-diketone complex to form a ternary complex, the ternary complex can be self-assembled in water to form a micellar structure, and then rare earth ions and ASPA are isolated through the collaborative protection on the rare earth ions by the ternary complex and the micellar structure, so that the aim of preparing a hydrogel which is good in luminescence property and high in mechanical strength is achieved. The hydrogel uses water as a medium, the preparation method is simple, easy and environmentally friendly, and a volatile organic solvent is avoided from being used. Please see the formula in the description.

Description

technical field

[0001] The invention belongs to the field of rare earth hybrid luminescent materials, and relates to a rare earth luminescent hydrogel, in particular to a preparation method of a high water content, high mechanical strength, self-repairing luminescent hydrogel.

[0002] technical background

[0003] Rare earth organic complexes have the advantages of strong light absorption ability, high luminous quantum efficiency, long fluorescence lifetime, good monochromatic performance, and rich emission spectrum. They play an extremely important role in the fields of luminescent materials, displays, OLEDs, etc. , Poor processability and other defects also limit the further functionalization and deviceization of rare earth complexes. Studies have shown that combining rare earth complexes with inorganic substrates such as zeolite and clay can effectively improve their light stability, thermal stability and processability. Among many matrix materials, hectorite can swell i...
