A Temperature‐Sensitive Luminescent Ag42 Nanocluster Supported by TertButyl Thiol Ligands

Compound [Ag42S5(StBu)25(CF3COO)4(CO3)](CO3)0.5⋅CH2Cl2⋅4CH3OH⋅9DMF (1) has been obtained and well defined. It consists of a multi‐shell structure involving two Ag centres, one Ag5S5 pentagram, two Ag5S5 pentagons and one Ag25S15 shell. Compound 1 has been characterized by XPS, FT‐IR, PXRD, TGA, NMR,...

Zusammenfassung:	Compound [Ag42S5(StBu)25(CF3COO)4(CO3)](CO3)0.5⋅CH2Cl2⋅4CH3OH⋅9DMF (1) has been obtained and well defined. It consists of a multi‐shell structure involving two Ag centres, one Ag5S5 pentagram, two Ag5S5 pentagons and one Ag25S15 shell. Compound 1 has been characterized by XPS, FT‐IR, PXRD, TGA, NMR, MS, UV/Vis spectrum, TEM and cyclic voltammetry. Temperature‐sensitive luminescent property of 1 has also been investigated. In a nutshell: The stable [Ag42S5(StBu)25(CF3COO)4(CO3)]+ ({Ag42S30} for short) nanocluster in 1 contains multi‐shell structure and exhibits temperature‐sensitive luminescence behavior has been obtained.
