A Temperature‐Sensitive Luminescent Ag42 Nanocluster Supported by Tert‐Butyl Thiol Ligands

: Compound [Ag42 S5 (StBu)25 (CF3 COO)4 (CO3 )](CO3 )0.5 ⋅CH2 Cl2 ⋅4CH3 OH⋅9DMF (1) has been obtained and well defined. It consists of a multi-shell structure involving two Ag centres, one Ag5 S5 pentagram, two Ag5 S5 pentagons and one Ag25 S15 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.
