摘要: 合成两系列12种钌铁多核配合物1~12,研究其电化学和光化学性质,发现配合物在450nm光的激发下产生的Ru(Ⅱ)上的单态激发态通过分子内能量传递和体系间窜迁过程分别形成Fe(Ⅱ)和Ru(Ⅱ)上2种三态激发态,在发射光谱中产生540nm和610nm两个发光位置.分子内能量传递过程的效率与配合物中Ru(Ⅱ)和Fe(Ⅱ)间的距离和配合物中Fe(Ⅱ)单元的个数有关.

Abstract: Akind of polynuclear ruthenium-ferrocene complexes [Fc-C(R)=N-(C6H4)n-N=C(C10H6N2)]m[Ru(bpy)3-m][(PF6)2] (R=H,CH3, n=0,1,2 and m=0,1,2) have been synthesized and characterized.The luminescence of the chromophore Ru(Ⅱ) is quenched by the luminophore Fe(Ⅱ), and efficient intramolecular energy transfer from the chromophore Ru(Ⅱ) to the luminophore Fe(Ⅱ) occurs in these bimetallic complexes.The efficience of the intramolecular energy transfer is related to the number of the luminophore Fe(Ⅱ) around the chromophore Ru(Ⅱ) and the distance between the Ru(Ⅱ) and Fe(Ⅱ) in the bimetallic complexes.

Key words: Ruthenium-ferrocene polynuclear complexes, Intramolecular energy transfer, Electrochemistry, Photochemistry
