英文摘要: Here we report a successful synthesis of water-soluble 13-atoms gold clusters under the monolayer protection of binary thiolates, glutathione and penicillamine, under a molecular formula of Au-13(SG)(5)(PA)(7). This monolayer-protected cluster (MPC) finds decent stability and is demonstrated to possess an icosa-hedral geometry pertaining to structural accommodation in contrast to a planar bare Au-13 of local minima energy. Natural bond orbital (NBO) analysis depicts the interaction patterns between gold and the ligands, enlightening to understand the origin of enhanced stability of the Au-13 MPCs. Further, the water-soluble Au-13 MPCs are found to be a decent candidate for chemosensing and bioimaging. (C) 2017 Elsevier B.V. All rights reserved.
