Problems solved by technology

[0004] According to the situation reported in the literature, the solvents that a gelling agent can form gels are often very limited, and usually can only form gels in commonly used organic solvents. It has not been found that a gelling factor can form gels in different commercial fuels. glue

Embodiment 1

[0035] Add 25mg (0.117mmol) of m-ditetrazolium benzene to a test tube with a stopper, add 0.117mmol of octadecylamine in another test tube, add 2mL of benzene solution, and heat in an oil bath until the solid is completely dissolved (the boiling point of benzene) Below 80°C), immediately mix the two and put them in the refrigerator to get a stable gel.

Embodiment 2

[0037] Add 25mg (0.117mmol) of m-ditetrazolium benzene to a test tube with a stopper, add 0.117mmol 3-hydroxypyridine to another test tube, add 2mL benzene solution separately, and heat in an oil bath until the solid is completely dissolved (benzene The boiling point is below 80°C), immediately mix the two and put them in the refrigerator to get a stable gel.

Embodiment 3

[0039] Add 25 mg (0.117 mmol) of m-ditetrazolium benzene to a test tube with a stopper, add 0.234 mmol 4-aminoimidazole to another test tube, add 2 mL of benzene solution, and heat in an oil bath until the solid is completely dissolved ( The boiling point is below 80°C), immediately mix the two and put them in the refrigerator to get a stable gel.

Abstract

The invention belongs to the field of supramolecular chemistry, and relates to dual-component micromolecular organic gels and a preparation method of the gels. The dual-component micromolecular organic gels comprise a first component which is a compound with one or a plurality of tetrazole groups, and a second component which can be various alkali compounds with amino, pyridine or imidazole groups; the first and second components are mainly subjected to intermolecular hydrogen bonding to form the gels; and the method for forming gel includes a heating method and an ultrasonic method. The gel factors can be used for immobilizing one or a plurality of common organic solvents to form stable gel, and also can form the gel under the commodity fuel solvent.

Description

technical field [0001] The invention belongs to the technical field of supramolecular chemistry, and in particular relates to a type of two-component small molecule organic gel and a preparation method of the organic gel. Background technique [0002] Gel is defined as a quasi-solid substance (soft substance) between solid and liquid. On the one hand, the specific network structure in the gel makes it unable to flow like a liquid; on the other hand, the existence of the liquid supports the specific network structure without collapsing. This coexistence of solid structure and liquid phase endows gels with unique elastic characteristics, which are different from solid and liquid materials in the traditional sense. Low Molar-mass Organic Gelators (LMOGs) refer to a class of small organic molecules that can gel organic solvents at relatively low concentrations. During the formation of the gel, LMOGs self-aggregate to form rod-like, ribbon-like, and fibrous structures through h...
