Abstract

The invention discloses a molybdenum-containing polyoxometalate and adamantane hybrid compound, which is prepared by connecting molybdenum-containing polyoxometalate and adamantane through a covalent bond. The preparation method comprises the following synthesis steps of: 1) performing amidation reaction on adamantane carboxylic acid serving as an initial raw material and trishydroxymethyl aminomethane to obtain N-trishydroxymethyl-adamantane carboxamide; and 2) reacting with the molybdenum-containing polyoxometalate to obtain the hybrid compound. By the invention, the molybdenum-containing polyoxometalate and the adamantine are connected through the covalent bond for the first time; and the synthesis method is simple and feasible, reaction conditions are easy to realize, purification is simple, and the yield is high. The hybrid molecule has potential application value in the aspects of medicines, lubricants, surfactants, catalysts and the like.

Description

technical field [0001] The invention relates to the preparation of a hybrid compound of polyoxometalate, in particular to an adamantane hybrid compound containing molybdenum polyoxometalate and a preparation method thereof. Background technique [0002] Polyoxometalates (Polyoxometalates, POMs, referred to as polyacids) are a class of unimolecular clusters formed by the connection of early transition metal atoms through oxygen coordination bridges, of which vanadium, molybdenum, tungsten and other elements are the main representatives. . The size of polyoxometalates is about 0.5nm-5nm, with rich chemical composition and various topological structures, and exhibits excellent properties in catalysis, medicine, and optical, electrical, and magnetic functional materials. With the development of modern synthesis technology and research methods, polyoxometallates with new structures emerge in endlessly, and new properties are constantly being discovered (see "Introduction to Hete...
