Abstract
Presented here is the synthesis and property study of a novel Cu(I) compound, namely, [Cu4(2-S-Bim)7(SO4)]n·n(SO4)·n(CH3CN)·2n(H2O) (1, 2-S-Bim=2-mercaptobenzimidazole). In this compound, 2-S-Bim ligand exhibits two different coordination modes: μ2-bridging mode and terminal coordination mode. Six 2-S-Bim ligands in μ2-bridging mode combined four Cu(I) ions together, affording a [Cu4S6] cluster. The remaining two coordination sites of Cu(I) ions in the [Cu4S6] cluster are occupied by one terminal 2-S-Bim ligand and one terminal SO42− anion, thus compound 1 exhibits a 0D isolated cluster-based framework. Moreover, this compound emits intense blue luminescence at room temperature. In addition, the as-produced compound’s application values against ischemia–reperfusion flaps were examined and the specific mechanism was tested simultaneously.
