AI Article Synopsis
- The study focuses on creating Ag nanoclusters that are protected by a compound called 2-pyrene imine thiol (2-PIT) using a method that involves altering ligands.
- Various analytical techniques, like spectroscopy and electron microscopy, were used to confirm the formation and composition of these nanoclusters.
- Notably, these nanoclusters exhibit both blue and near-infrared (NIR) emissions under UV light, marking a significant breakthrough as it's the first report on dual-emitting silver nanoclusters with such precise atomic structures.
Article Abstract
In this communication, we present the synthesis of 2-pyrene imine thiol (2-PIT)-protected Ag nanoclusters using a ligand exchange-induced structural transformation reaction. The formation of the nanocluster and its composition were confirmed through several spectroscopic and electron microscopic studies. The UV-vis absorption spectrum showed a set of characteristic features of the nanocluster. This nanocluster showed blue emission under UV light due to pyrene to metal core charge-transfer, and NIR emission due to charge-transfer within the metal core. This is the first report on dual emitting pyrene protected atomically precise silver nanoclusters.
