Embodiment 1

[0043] Example 1: A preparation method of a symmetrical tetramethyl six-membered citrullus ring supramolecular framework material is to add the symmetrical tetramethyl six-membered cucurbit ring to a 2M HCl solution and heat to dissolve it until the solution is transparent, and then wait for the solution After cooling, a transparent precipitate is naturally precipitated, and the liquid is filtered off by suction to obtain a precipitate. After the precipitate is dried, a symmetrical tetramethyl six-membered citrulline supramolecular framework material can be obtained.

Embodiment 2

[0044] Example 2: A preparation method of a symmetrical tetramethyl six-membered citrullus ring supramolecular framework material is to add the symmetrical tetramethyl six-membered citrullus ring to a 1.5M HCl solution and heat to dissolve it until the solution is transparent. After the solution is cooled, a transparent precipitate is naturally precipitated, and the liquid is filtered by suction to obtain a precipitate. After the precipitate is dried, a symmetrical tetramethyl six-membered citrulline supramolecular framework material can be obtained.

Embodiment 3

[0045] Example 3: A preparation method of symmetrical tetramethyl six-membered citrullus ring supramolecular framework material is to add the symmetrical tetramethyl six-membered citrullus ring to a 2.5M HCl solution and heat to dissolve it until the solution is transparent. After the solution is cooled, a transparent precipitate is naturally precipitated, and the liquid is filtered by suction to obtain a precipitate. After the precipitate is dried, a symmetrical tetramethyl six-membered citrulline supramolecular framework material can be obtained.

Abstract

The invention discloses a symmetric tetramethyl hexatomic cucurbituril super-molecular frame material, a preparation method and application thereof. The monomer molecular formula of the symmetric tetramethyl hexatomic cucurbituril super-molecular frame material is C40H44O12N24. The symmetric tetramethyl hexatomic cucurbituril super-molecular frame material is prepared according to the following steps: adding symmetric tetramethyl hexatomic cucurbituril into HCl solution, heating till dissolving, cooling the solution and then separating out a transparent solid, and lastly, filtering the liquid.The frame material is prepared into a fluorescent material which is used for detecting ethyl alcohol and dichloromethane, acetone, benzene or trichloromethane in air. The frame material disclosed bythe invention has the characteristics that the frame material can be prepared into the fluorescent material and can be used for detecting ethyl alcohol and dichloromethane, acetone, benzene or trichloromethane in air. In addition, after the symmetric tetramethyl hexatomic cucurbituril super-molecular frame material disclosed by the invention is prepared into the fluorescent material and absorbs the identified molecules, the frame material can be recycled.

Description

Technical field [0001] The invention relates to a cucurbital supramolecular frame material and a preparation method and application thereof, in particular to a symmetrical tetramethyl six-membered citrulline supramolecular frame material and a preparation method and application thereof. Background technique [0002] Cucurbit[n]uril, also known as cucurbituril, (abbreviated as CB[n] or Q[n]), is a kind of macrocyclic compound bridged by n glycoside units and 2n methylene groups , Because its structure resembles pumpkin and is a cyclic compound, hence the name melon ring. The six-membered melon ring, the first member of the family since 1981 [0003] Since the structure of (Cucurbituril,Q[6]) was determined, the Cucurbit[n]urils,Q[n]s family has been prosperous, and related cucurbital chemistry research has also achieved remarkable results. progress. Especially the research on the modification of melon ring has greatly promoted the application of melon ring in various fields. [00...
