摘要
合成了一个新颖的多吡啶配体二吡啶并[3,2-a:2',3'-c]吡嗪并-15-冠-5(L)和相应的配合物[(bpy)2RuL](PF6)2(1)[Ru(L)3](PF6)2(2).配合物与Na+的结合性能通过荧光、紫外可见吸收光谱、循环伏安法进行研究.当把钠离子加入到配合物1和2的乙腈溶液中,配合物的荧光强度逐步增强、紫外可见吸收产生增色效应、基于钌(II)中心的氧化还原电对向阴极移动.
A novel polypyridyl ligand dipyrido[3,2 - a:2',3'- c] phenazo - 15 - crown - 5 (L) and corresponding complexes [ ( bpy)2 RuL ] ( PF6 )2 ( 1 ) and [ Ru ( L)a ] ( PF6 )2 (2) have been synthesized. The photophysical behavior and the binding ability of the complexes with Na+ were investigated by fluorescence, UV -Vis spectrometry and cyclic vohammetry. The addition of Na+ to the CH3CN solution of 1 and 2 all result in a progressive enhancement of the fluorescence intensity, a hyperchromic effect of the UV - Vis absorption, and cathodal shift of Ru (Ⅱ) -centered redox couple.
