摘要：
A series of phosphinocrown ether-containing gold(I) complexes, [Au(Ph2P-b15c5)Cl] (1), [Au-2(mu-i-mnt)(Ph2P-b15c5)(2)] (2) and [Au-2(mu-dtc)(Ph2P-b15c5)(2)](PF6) (3) (b15c5 = benzo-15-crown-5, i-mnt(2-) = 1,1-dicyanoethylene-2,2-dithiolate, dtc(-) = diethyldithiocarbamate) have been synthesized. Complexes 2 and 3 center dot NaPF6 have also been structurally characterized. The emission bands at ca. 500-515 nm for 2 and 3 upon photo-excitation are tentatively assigned as derived from excited states of S -> Au ligand-to-metal charge transfer (LMCT) origin. These complexes have been shown to serve as host for the specific binding of various metal cations. (c) 2005 Elsevier B.V.. All rights reserved.
