A series of seven luminescent copper(I) dithiophosphonate (dtp) clusters of the type CuL (L = SPR(OR')) were formed from CuCl·2HO precursor in aqueous medium under ambient conditions. The dtp ligand serves the dual function of acting as a sacrificial reducing agent and cluster core stabilizer. The new clusters were characterized by H and P NMR and ESI-MS, and the single-crystal X-ray structures for two representative clusters [Cu{(SP(1,4-CHOMe)(OR')}] (R' = OCH(CH); CHCH) were determined. The redox reaction yielded clusters in satisfactory yield, and all exhibited luminescence with λ in the range 519-534 nm and half-lives in the range 10-14 μs.
在环境条件下，由CuCl·2H₂O前体在水性介质中形成了一系列七个类型为CuL（L = SPR(OR')）的发光二硫代膦酸铜（I）簇。二硫代膦酸配体起到牺牲还原剂和簇核心稳定剂的双重作用。通过¹H和³¹P NMR以及ESI-MS对新簇进行了表征，并确定了两个代表性簇[Cu{(SP(1,4-CH₂OMe)(OR')}]（R' = OCH(CH₃)₂；CH₂CH₃）的单晶X射线结构。氧化还原反应以令人满意的产率生成簇，并且所有簇都表现出发光，λ在519 - 534 nm范围内，半衰期在10 - 14 μs范围内。
