摘要：
(Chemical Equation Presented) Give and take: Compound 1 (see structure: purple Pt, red Fe, green P, blue O; Fc = [η-C5H 5)Fe(η-C5H4)]) is prepared in good yields by the Cul-catalyzed coupling of two equivalents of ethynylferrocene with the hexanuclear cluster [Pt6(μ-PtBu2)4(CO) 4Cl2]. Electrochemical and spectroelectrochemical data show the presence of photoelectrochemically triggered electron transfer from the {Pt6} core to the peripheral ferrocenyl subunits. © 2005 Wiley-VCH Verlag GmbH & Co.
