摘要

Five new transition metal complexes, formulated as [Zn(DMBPIP) _3](PF _6) _2 (1), [Ni(DMBPIP) _3](PF _6) _2 (2), [Co(DMBPIP) _3](PF _6) _2 (3), [Fe(DMBPIP) _3](PF _6) _2 (4), [Ru(DMBPIP) _3](PF _6) _2 (5) {where DMBPIP = 2-(3′,5′-dimethoxybiphenyl-4-yl)-1H-imidazo[4,5-f] [1,10]phenanthroline} were synthesized and characterized by means of elemental analysis, IR, ~1H NMR, ~(13)C{~1H} NMR, standard spectroscopy techniques and cyclic voltammetry. The pH effects on UV-Vis absorption and luminescence spectra of the Zn(II) and Ru(II) complexes are studied, and ground- and excited-state ionization constants of the two complexes are derived. The two complexes acting as pH-induced "off-on-off" luminescence switches through protonation and deprotonation in buffer solution at room temperature are studied and discussed as well.
