“…[39][40][41][42][43][44][45][46][47] For example, in the synthesis of Au-Ag alloy clusters using mixed ligands ( phosphorus and halogen ligands), Au preferentially connects to P while Ag preferentially bonds to the halogen owing to the difference in binding energies. 15,23,[48][49][50][51][52][53] However, this strategy did not work in homologated clusters. The ability to precisely control the doping position in homologated nanoclusters is challenging as well as extremely important for studying the structureactivity relationship.…”

The solvent plays an influential role in controlling the nucleation process of metal nanoclusters (MNCs) and thereby significantly modulates their optical signatures. Herein, we have demonstrated the solvent‐induced modulation in the optical properties of copper nanoclusters (CuNCs), primarily governed by the solvent polarity. During the preparation of para‐mercaptobenzoic acid (p‐MBA)‐templated CuNCs, the simultaneous formation of blue‐emitting CuNCs (B‐CuNCs) and red‐emitting CuNCs (R‐CuNCs) were observed up to 7 h of reaction time, reflected from the systematic increment in the photoluminescence (PL) intensity at 420 nm and 615 nm, respectively. However, after 7 h of reaction time, the exclusive formation of B‐CuNCs was observed. Such simultaneous growth and depletion dynamics of CuNCs result in a significant modulation in their optical properties. The variation of the solvent from water to less polar solvents such as DMSO and DMF restricts this inter‐cluster dynamics by stabilizing both the CuNCs (B‐CuNCs and R‐CuNCs). Thereby, a single‐component White Light Emission (WLE) was realized in DMSO with CIE coordinates (0.37, 0.36). The isomeric effect of the templates has also been investigated which extensively controls the optical and catalytic properties of the CuNCs.

The presence of DMSO provides a unique ability to stabilize silver toroidal complexes in the direct reaction between AgStBu and AgNO3 at 80 °C. Slow cooling results in large crystals of [NO3@Ag19.2(StBu)10(DMSO)5.2(NO3)8.2]·3DMSO (1), which were isolated and characterized by single crystal X-ray diffraction (SCXRD) analysis. The crystal structure contains both {Ag20(StBu)10} and {Ag19(StBu)10} clusters. The solution of these material in DMSO was studied with HPLC techniques, which demonstrated the presence of both complexes in solution. The use of [SiW12O40]4– as counter anion gives crystals of a double complex salt [Ag17.8(NO3)3.8(StBu)10][SiW12O40]·30DMSO (2) under the same conditions. Temperature-dependent photoluminescence (PL) was studied.
