Dominating Role of 2‑Mercaptobenzothiazole as a Capping Ligand in Silver Nanocluster Synthesis.

ABSTRACT: This work highlights the dominating role of the capping ligand 2-mercaptobenzothiazole (2-MBT) in the synthesis of a silver nanocluster (AgNC). AgNC was synthesized through ligand exchange (LE) in a two-phase reaction system by reacting a preformed water-soluble glutathione (GSH)-stabilized silver nanocluster (Ag-SGNC) with 2-MBT dissolved in dichloromethane. We observed the formation of a fluorescent AgNC in the organic phase from the nonfluorescent Ag-SGNC. The composition of the nanocluster was determined with the help of UV-vis spectroscopy, Fourier transform infrared spectroscopy, fluorescence spectroscopy, powder X-ray diffraction, X-ray photoelectron spectroscopy, MALDI mass spectrometry, and thermogravimetric analysis. We recently synthesized Ag₁₆(2-MBT)₁₂ clu
