“…We have previously described selective sensing by photoluminescent coinage metal clusters stabilized by multidentate phosphine ligands. − Our work included the reaction of Ag(I) salts with N , N′ -bis(diphenylphosphanylmethyl)-ethylenediamine (bdppeda) that led to the in situ formation of two new ligands, viz N , N ′-bis(diphenylphosphanylmethyl)-tetrahydroimidazole (bdppthi) and its cationic oxidation product N , N ′-bis(diphenylphosphanylmethyl)-3 H -4,5-dihydroimidazole-1-ium (bdppdhii + ) . Ag–Cu clusters stabilized with bdppthi exhibited selective quenching of emission on exposure to ammonia .…”

Luminescent materials with aggregation-induced emission (AIE) characteristics have been recognized as highly selective and sensitive probes for the detection of toxic metal ions in recent years. In this paper, a Au−Ag cluster-based coordination polymerwas prepared by in situ generation of the diphosphine N-heterocyclic carbene (PC NHC P)-type ligand L in the presence of the corresponding metal salts. Compound 1 exhibited 530 nm phosphorescence under 380 nm excitation with a QY of 6.30% and a lifetime (τ) of 7.14 μs in the solid state. 1 showed good AIE behavior in the mixture of MeOH/H 2 O while the best aggregation state (f water = 90%, QY = 6.79%, τ = 6.70 μs) exhibited selective and sensitive emission quenching toward Cr(VI) ions. Ultralow detection limits of 9.7 ppb (w/ w) for Cr 2 O 7 2− and 17.9 ppb (w/w) for CrO 4 2− were achieved.

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).
