Fig. 1. Time-dependent UV-vis absorption spectra for tracking the reaction process. Experimental method: 9 mg {Ag(SⁱPr)}_n, 22 mg CF₃COOAg, and 50 μL CF₃COOH in the solvent mixture (ⁱPrOH : DMF = 3 : 1) at 80 °C. Inset: the colour of mother liquor after the solvothermal reaction at different times (1–24 h).
