Although ionic liquids (ILs) are of prime interest for the synthesis of various nanomaterials, they are scarcely utilized for the polyhydrido copper(I) [Cu(I)H] clusters. Herein, two air-stable Cu(I)H clusters, CuH(dppy) (CuH) and {CuH(dppy)[N(CN)]} (CuH), are synthesized in high yields for the first time from the ILs-driven conversion of an unprecedented cluster CuH(dppy) (CuH) by a facile three-layers diffusion crystal (TLDC) method, strategically introducing IL-NTf and IL-N(CN) as two types of unusual interfacial crystallized templates, respectively. Their structures are fully characterized by various spectroscopic methods and X-ray crystallography, which shows that the anion of IL plays an important role as an anion template and an anion ligand in controlling the structural conversion of Cu(I)H clusters. Their photophysical properties are also investigated, and it is found that all reported clusters exhibit red luminescence with λ ranging from 600 to 690 nm.
尽管离子液体（ILs）在各种纳米材料的合成中备受关注，但它们很少用于多氢铜（I）[Cu（I）H]簇合物。在此，首次通过简便的三层扩散晶体（TLDC）方法，由离子液体驱动前所未有的簇合物CuH（dppy）（CuH）转化，以高产率合成了两种空气稳定的Cu（I）H簇合物，CuH（dppy）（CuH）和{CuH（dppy）[N（CN）]}（CuH），分别策略性地引入IL-NTf和IL-N(CN)作为两种不同寻常的界面结晶模板。通过各种光谱方法和X射线晶体学对它们的结构进行了全面表征，结果表明离子液体的阴离子在控制Cu（I）H簇合物的结构转化中作为阴离子模板和阴离子配体发挥着重要作用。还研究了它们的光物理性质，发现所有报道的簇合物都表现出红色发光，波长范围为600至690nm。
