Pentanuclear copper (I) complex with core-shell-like structure as well as preparation method and application of pentanuclear copper (I) complex

The invention relates to a pentanuclear copper (I) complex with a core-shell-like structure and a preparation method and application thereof.The molecular formula of the pentanuclear copper (I) complex with the core-shell-like structure is [C112H82Cu5S4N22P4] PF6, and the molecular weight is 2469.78. The preparation method comprises the steps that a pyridoimidazole diphosphine ligand L and an auxiliary ligand 1-phenyl-1H-tetrazole-5-mercaptan are added into a mixed solvent of CH2Cl2 and CH3OH, stirring is conducted for 1-2 h, and the pentanuclear copper (I) complex with the core-shell-like structure is obtained; uniformly stirring to obtain a mixed solution; adding [Cu (CH3CN) 4] PF6 into the mixed solution, stirring at normal temperature, filtering into a culture bottle, and slowly volatilizing filtrate in the culture bottle at room temperature to obtain transparent faint yellow crystals; and washing the obtained crystal with absolute ethyl alcohol, and performing vacuum drying. The preparation method is mil
