WebAbstract. In this paper, we report a highly stable gold nanocluster co-protected by the selenophenol and 1,5-bis (diphenylphosphino)pentane (L 5 for short) ligands, formulated … WebThe structure of this nanocluster is determined by X-ray crystallography. The L 5 -ligands are in the form of “Au–PPh 2 (CH 2) 5 Ph 2 P–Au”, similar to the “staple motif” in the Au n (SR) m nanoclusters. The purity of this nanocluster is confirmed by electrospray ionization mass spectrometry (ESI-MS) and the thermogravimetric analysis (TGA).
