Abstract

The invention provides a preparation method for N,N'-ferrocenediacetyl-tri(dodecyloxy) benzamide, and belongs to the field of synthesis of functionally micromolecules. The method comprises the following steps: taking methyl gallate, bromododecane and ferrocene as reaction raw materials, firstly performing substitution and hydrazinolysis on methyl gallate to generate 3,4,5-tri(dodecyloxy)benzoyl hydrazine; performing acylation, acidification and acyl chlorination on ferrocene to generate 1,1'-ferrocenedicarbonylchloride; and finally reacting 3,4,5-tri(dodecyloxy)benzoyl hydrazine with 1,1'-ferrocenedicarbonylchloride, so as to obtain N,N'-ferrocenediacetyl-tri(dodecyloxy)benzamide. The method possesses the characteristics of being mild in reaction conditions, simple in operation, low in cost, high in yield and high in product purity. Additionally, the N,N'-ferrocenediacetyl-tri(dodecyloxy)benzamide possesses good gelling effect and possesses good market application prospect.

Description

technical field [0001] The invention relates to the field of functional small molecule synthesis, in particular to a preparation method of N,N'-ferrocene diacetyl-tris(dodecyloxy)benzamide. Background technique [0002] In recent years, molecular gels, as an important branch of colloid science, have attracted more and more attention based on their unique supramolecular multilevel self-assembly structure and broad potential application prospects. After more than 30 years of rapid development, supramolecular chemistry has become a new discipline that intersects with biology, physics, materials and other disciplines. Recent studies have found that the introduction of some special functional groups on the gel factor can prepare gel materials that are stimuli-responsive to light, electricity, heat, ultrasound, fluorescence, pH, magnetism, fluorine ions, etc. It has huge potential application value in various photosensitive devices, biomaterials, drug delivery, nanomaterial prepa...
