Problems solved by technology

Hexamethyl six-membered cucurbit ring is a low-content product in the process of cucurbit ring synthesis. In 2003, the Day research group reported the separation and characterization of hexamethyl six-membered cucurbit ring for the first time, but due to low yield and difficult separation, etc. , limiting its development and application
However, its application to fluorescent materials has not been reported
[0003] At the same time, there are many types of existing fluorescent materials, but there are defects such as complicated preparation process and high processing cost.

Abstract

The invention discloses a hexamethyl six-membered cucurbituril supramolecule self-assembled carrier and application thereof. The hexamethyl six-membered cucurbituril supramolecule self-assembled carrier is prepared from hexamethyl six-membered cucurbituril and a neutral aqueous solution which are used as raw materials. The carrier is of a multi-pore framework structure self-assembled on the basisof hexamethyl six-membered cucurbituril supramolecules. The structure can be used for preparing various solid fluorescent materials. The fluorescent material has a specific identification effect on specific volatile gas, and can be used for blending fluorescent materials in different colors, so that application of the hexamethyl six-membered cucurbituril is expanded. In addition, the fluorescent material of the invention has the characteristics of simple preparation process and low manufacturing cost.

Description

technical field [0001] The invention relates to the application of a hexamethyl six-membered cucurbit ring, in particular to a porous framework structure based on the hexamethyl six-membered cucurbit ring supramolecular self-assembly and its application. Background technique [0002] Cucurbit[n]uril, also known as cucurbit[n]uril, (abbreviated as CB[n] or Q[n]), named for its structure resembling pumpkin, is a macrocycle following crown ether, cyclodextrin and calixarene. Another new type of cage-like host compound after the compound. From the perspective of structural properties, the cucurbit ring has a highly symmetrical hydrophobic cavity and open and full of polar carbonyl oxygen atoms. The above characteristics of this structure make It can selectively include small molecules such as organic, inorganic and biomolecules of appropriate size in the solution state, or have a hydrophilic coordination with dipole or ionic compounds at the port. With the research With the dee...
