摘要
正文。利用(PPh_4)_2[Ru~II(PPh_3)_2(CN)_4](1)与bpyOH和phenOH分别反应得到两个单核的化合物fac–(PPh_4)[Ru~II(bpyOH)(PPh_3)(CN)_3](2)和fac–(PPh_4)[Ru~II(PhenOH)(PPh_3)(CN)_3](3)。化合物1和2的晶体结构通过单晶衍射仪得到确认。化合物2和3的光学性能得到了仔细的研究。其中化合物3在脱氧的CH2Cl2的量子产率为19.4%,远高于同类别的其它化合物。化合物2和3都展现出独特的溶剂化、pH以及离子效应。
Treatment of(PPh_4)_2[Ru~II(PPh_3)_2(CN)_4](1) with bpyOH and phenOH in DMF afforded two mononuclear compounds fac–(PPh_4)[Ru~II(bpyOH)(PPh_3)(CN)_3](2) and fac–(PPh_4)[RuII(PhenOH)(PPh_3)(CN)_3](3), respectively. These complexes have been characterized using various spectroscopic techniques. Structures of 1 and 2 have also been determined by X–ray crystallography. Their photophysical and electrochemical properties have been investigated. Detailed study showed that 3 displays intense emission in CH_2Cl_2 at 298 K(Φem = 19.4%) with much higher emission efficiency, compared with other related ruthenate(II) diiminecomplexes. In addition, their solvatochromism, pH effect, ion perturbation have also been investigated. The p Ka value and dynamic pH response range have been determined. Their photophysical response towards various metal ions such as Zn~(2+), Cd~(2+), Fe3+, Cu~(2+), Mg~(2+), Ca~(2+), Na~+, K~+, Ni~(2+), Mn~(2+)and Co~(2+) have also been studied by different spectroscopic methods.
