Abstract

Reaction of a P/N/S hybrid ligand dpppyatc (N,N-bis((diphenylphosphaneyl)methyl)-N-(pyridin-2-yl)-amino-thiocarbamide) with Au(tht)Cl (tht=tetrahydrothiophene) and [Cu(MeCN)₄]BF₄ afforded cluster complex [Au₂Cu(dpppyatc)₂](BF₄)₂Cl (1). Upon excitation at 480 nm, 1 emitted orange phosphorescence at 646 nm, which was red-shifted to ~698 nm selectively in the presence of ammonia or amine vapor. This chromic photoluminescent response toward ammonia was sensitive and reversible. Complex1 could detect ammonia in aqueous solution down to concentrations of 2 ppm (w/w).

一种磷光 P/N/S 混合配体稳定的 Au2Cu 复合物可选择性地感知氨和胺。

P/N/S 混合配体 dpppyatc（N,N-双((二苯基膦烷基)甲基)-N-(吡啶-2-基)-氨基-硫代甲酰胺）与 Au(tht)Cl（tht = 四氢噻吩）和 [Cu(MeCN)4]BF4 反应生成了簇状复合物 [Au2Cu(dpppyatc)2](BF4)2Cl（1）。在 480 纳米波长的激发下，1 发出 646 纳米波长的橙色磷光，在氨或胺蒸气存在下，该磷光会选择性地红移到约 698 纳米波长。这种对氨的色谱光致发光反应灵敏且可逆。Complex1 可以检测水溶液中浓度低至 2 ppm（w/w）的氨。

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
