Description

technical field [0001] The invention relates to the technical field of cluster preparation, in particular to a tetranuclear silver heterometallic cluster and a preparation method thereof. Background technique [0002] Heterometallic clusters refer to coordination compounds containing two or more metals in their molecules. Because of their novel and changeable structures, and their excellent properties in light, electricity, magnetism and catalysis, they have received a lot of attention. favored by researchers. Ferrocene molecules with redox activity can be modified on the surface of silver clusters or silver multi-nuclear clusters by means of coordination, which can often improve the photoelectric activity of silver-containing compounds and greatly increase the possibility of their application in the field of optoelectronics. sex. For example, John F. Corrigan's research group has successively used ferrocene sulfhydryl / selenium ligands to modify ferrocene molecules on the ...
