A new Ag/Cu bimetallic cluster AgCu(bdppthi)(C≡CPh)(EtOH) (, bdppthi = ,-bis(diphenylphosphanylmethyl)-tetrahydroimidazole) exhibited strong phosphorescent (PL) emission at 644 nm upon excitation at 400 nm. Removal of the coordinated EtOH molecules in resulted in derivative , which exhibited significant red-shifted emission at 678 nm. The structure and PL of was restored on exposure to EtOH vapor. Cluster also exhibited a vapor-chromic PL response towards other common organic solvent vapors including acetone, MeOH and MeCN. A PMMA film of was developed as a reusable visible sensor for MeCN.
一种新型的 Ag/Cu 双金属簇合物 [AgCu(bdppthi)(C≡CPh)(EtOH)] (ClO)（bdppthi = ，-双（二苯基膦基）甲基）-四氢咪唑），在 400nm 激发下，在 644nm 处表现出强磷光（PL）发射。在 中去除配位的 EtOH 分子得到衍生物 ，其在 678nm 处表现出显著的红移发射。在暴露于 EtOH 蒸气时，结构和 PL 得到恢复。簇合物 也表现出对其他常见有机溶剂蒸气（包括丙酮、甲醇和乙腈）的蒸气变色 PL 响应。开发了一种含有 的 PMMA 薄膜作为乙腈的可重复使用的可见传感器。
