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 melon ring supramolecular self-assembly carrier and its application. The hexamethyl six-membered melon ring supramolecular self-assembly is prepared by using the hexamethyl six-membered melon ring and a neutral aqueous solution as raw materials carrier. The carrier is a porous framework structure based on hexamethyl six-membered cucurbit ring supramolecular self-assembly, which can be used to prepare a variety of solid fluorescent materials, which not only show specific recognition for specific volatile gases, but also It can also be used to prepare fluorescent materials of different colors, expanding the application of the hexamethyl six-membered melon ring; in addition, the fluorescent material of the present 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...
