Abstract

The invention belongs to the supermolecule chemical technology field, more particular, relates to a low molecular weight organogel and a preparing method of the low molecular weight organogel. The low molecular weight organogel of the invention is prepared by dissolving a low molecular weight organogel agent in an organic solvent under heating, and then cooling to the ambient temperature or a low temperature (wherein the heating temperature is lower than the boiling point of the organic solvent; the cooling temperature is higher than the freezing point of the organic solvent); wherein, the concentration of the low molecular weight organogel agent in the organic solvent is 0.1wt%-10wt%.

Description

technical field [0001] The invention belongs to the technical field of supramolecular chemistry, and in particular relates to a class of low molecular weight organogels and a preparation method of the organogels. Background technique [0002] Certain small molecular organic compounds can gel organic solvents at very low concentrations to form organic gels (Oranogel). This kind of small molecular compound is called low molecular weight organic gelling agent (Low Molecular Weight Gelator). The gelling agent is heated and dissolved in the solvent. The intermolecular interactions self-assemble to form fibrous structures, and these fibrous structures are further entangled to form a three-dimensional network structure, so that the solvent molecules lose their fluidity through the liquid-solid interfacial tension to form a gel. This kind of supramolecular gel is different from the gel formed by polymers, which belongs to physical gel, and has thermoreversibility, which is currentl...
