Abstract

The invention pertains to the technical field of nanometer supramolecular materials, and relates to a nanometer supramolecular assembly of a perylene diimide derivate modified by full methylated Beta-cyclodextrin loaded by polyvinylidene fluoride membrane and a preparation method thereof. The chemical formula of the molecular assembly is C138H226N2O72, and the structure thereof is shown as in an attached drawing. The perylene diimide derivate modified by the red fully methylated Beta-cyclodextrin is dissolved to obtain the nanometer supramolecular assembly. The method adopts the strong fluorescence of solid perylene as a detecting singnal, takes an empty chamber of the fully methylated Beta-cyclodextrin as a receptor of an air molecule, thereby solving two difficulties of strong fluorescence in a solid state in the construction of a fluorescence sensor and the introduction of a suitable air molecular receptor. The nanometer supramolecular assembly of the perylene diimide derivate modified by full methylated Beta-cyclodextrin loaded by PVDF member realizes quick detection of the fluorescence sensing function of the air molecules of nitromethane, nitroethane and nitrobenzene in 10s.

Description

【Technical field】

[0001] The invention belongs to the technical field of nano-supramolecular materials, and relates to a perylene diimide derivative nano-supramolecular assembly loaded with fully methylated β-cyclodextrin on a PVDF membrane and a preparation method thereof. 【Background technique】

[0002] The construction and application of fluorescent sensors under solid-state conditions are research hotspots in recent years. The construction of fluorescent sensors to realize the recognition of gas molecules, especially the recognition of volatile flammable and explosive nitro compounds has made great progress (S.W.Thomas III, G.D.Joly, T.M.Swager.Chem.Rev.2007 , 107, 1339-1386; (2) D.T.McQuade, A.E.Pullen, T.M.Swager.Chem.Rev.2000, 100, 2537-2574; (3) S.J.Toal, W.C.Trogler.J.Mater.Chem., 2006, 16 , 2871-2883.). Two problems need to be overcome in the construction of fluorescent sensors: one is to synthesize organic compounds with strong fluorescence under solid-state con...
