Abstract

A thiophosphite of Cu contained transition metal mixture has a chemical formula CuxMyP2S3, where M is Mn, Fe, Ni and Cd, x=0-1.5, y=0-1.0 and z=0.5-1.0. It has excellent electric conductivity and can be used to prepare the intercalation compound and multifunctional molecular material with high photoelectric activity. Its preparing process is also disclosed.

Description

technical field [0001] The present invention relates to copper-containing mixed transition metal thiophosphites Cu x m y P z S 3 (M=Mn, Fe, Ni, Cd) and its preparation method and use. Background technique [0002] Transition metal thiophosphite, as a class of two-dimensional layered materials, exhibits many special physical and chemical properties different from three-dimensional materials, such as strong electrical anisotropy and two-dimensional magnetic anisotropy, etc. These properties originate from Because of their two-dimensional layered structural characteristics; and some intercalation (intercalation) compounds formed based on this structural characteristic exhibit different properties from pure transition metal thiophosphites in terms of electricity, magnetism, light and catalysis. The excellent properties make it a better idea and method for designing and synthesizing molecular-based opto-electromagnetic materials. [0003] For a long time, the preparation of ...
