双核钌配合物中金属间相互作用的电化学研究
, PP. 167-172
Keywords: 双核钌(Ⅱ)配合物,去质子化,电化学性质,电子相互作用
Abstract:
应用循环伏安、循环交流伏安和微分电容测定等电化学方法研究了由2,2一联吡啶(bpy)和桥联配体1,4_二[2_咪唑并[4,5_f]邻菲咯啉]苯(DIPB)或1,4_二[2_脱氢咪唑并[4,5_f]邻菲咯啉]苯(DIPB_2H)所形成的对称双核钌配合物(Ru2:(bpy)2Ru(DIPB)Ru(bpy)2(ClO4)4和Ru2_2H:(bpy)2Ru(DIPB_2H)Ru(bpy)2(ClO4)2)在铂电极上的电化学性质以及金属间的相互作用.研究结果表明,在0.1mol/L高氯酸四丁基铵(TBAP)的乙腈溶液中,中心离子在循环伏安图上均呈现1对可逆的2电子氧化还原波,电位也几乎不变,其所对应的配位阳离子的扩散系数分别为3.50×10-6cm2/s和3.94×10-6cm2/s.循环交流伏安和微分电容测定研究发现,桥联配体去质子化后,中心离子间的电子相互作用增强
