Abstract

The invention discloses a photosensitive material with Anderson type polyacid and a preparation method thereof, which belong to the technical field of the preparation of polyacid functional materials. The preparation method comprises the steps of: firstly preparing a series of organic molecular long-chains with active chemical function groups; secondly, preparing the Anderson type polyacid modified by the function groups; and finally, grafting the derived Anderson type polyacid with the organic molecular long-chains through covalent bonds. By the method, the preparation of photosensitive materials with the Anderson type polyacid for the first time is realized, and the application field of polyoxometallate is expanded. The method has the advantages of simple preparation process, good repeatability, high yield and strong operability.

Description

technical field [0001] The invention belongs to the technical field of preparation of polyacid functional materials, in particular to a photosensitive material containing Anderson type polyacid and a preparation method thereof. Background technique [0002] In recent years, the development of novel functional-oriented polyacid molecular assembly materials has gradually become the core of international polyacid chemistry research. Polyoxygen compounds (POMs) are a class of multimetal oxides containing V, Mo, W and other metals. Isopolyanions formed by the condensation of the same oxoacid ions are called isopolyacids. The condensation of different types of oxyacid anions is called heteropolyanion, and the acid is called heteropolyacid. At present, it is known that the atoms of nearly 70 kinds of elements can be used as heteroatoms in heteropolyacids, including all the first series transition elements, almost all the second and third series transition elements, plus B, Al, Ga...
