摘要: Abstract A series of aromatic ethynyl-bridged ferrocenes with the general formula Fc–CC–R–CC–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 reaction ethynyl ferrocene appropriate dibromo-arenes. The new complexes have characterised spectroscopic techniques. structures 3 7 were determined via X-ray crystallography, both show trans–trans configuration two groups respect to central R group. electronic properties compounds studied optical spectroscopy cyclic voltammetry.
