Bis-[methylsalicylidine-4'benzoic acid]-ethylene (LH2) complexed with cis-Ru(bpy)2Cl(2).2H2O provides a complex of composition [Ru(bpy)2L].2NH4PF6 (1), which has been characterized spectroscopically. Its binding behaviour towards Mg2+ and Ca2+ ions is monitored using 1H NMR titration, isothermal titration calorimetry (ITC) and luminescence microscopy. The luminescent ruthenium complex binds Ca2+ in a more selective manner as compared to Mg2+.
双-[甲基水杨醛-4'-苯甲酸]-乙烯(LH2)与顺式-Ru(bpy)2Cl(2).2H2O 络合得到组成为[Ru(bpy)2L].2NH4PF6 的络合物(1),该络合物已通过光谱进行了表征。使用 1H NMR 滴定、等温滴定量热法(ITC)和发光显微镜监测其对 Mg2+和 Ca2+离子的结合行为。与 Mg2+相比,发光钌络合物以更具选择性的方式结合 Ca2+。
