摘要：

A series of aromatic ethynyl-bridged ferrocenes with the general formula Fc-CdropC-R-CdropC-Fc (Fc = ferrocenyl, R = C6H2(-p-CH3)(2) (1), C6H4-p-C6H4 (2), C5H3N (3), 9,10-C14H8 (4), C4H2S (5), (C4H2S)(2) (6) and (C4H2S)(3) (7)) has been synthesised by the reaction of ethynyl ferrocene with the appropriate dibromo-arenes. The new complexes have been characterised by spectroscopic techniques. The structures of 3 and 7 were determined via X-ray crystallography, and both show the trans-trans configuration of the two ethynyl ferrocene groups with respect to the central R group. The electronic properties of the compounds have been studied via optical spectroscopy and cyclic voltammetry. (C) 2004 Elsevier B.V. All rights reserved.
