英文摘要：

Ruthenium（Ⅱ） phenanthroline complexes with different functional groups： [Ru（bpy）2（phen- NO2）]（PF6）2 （1）, [Ru（bpy）2（phen-Br）]（PF6）2 （2）, [Ru（bpy）2（phen-NH2）]（PF6）2 （3）, [Ru（bpy）2（bphen）]（PF6）2 （4） （where bpy= 2,2＇-bipyridyl, phen-NO2= 5-nitro-phenanthroline, phen-Br= 5-bromo-phenanthroline, phen_NH2=5_amino_phenanthroline, bphen=bathophenanthroline） were synthesized. They were characterized and analyzed by NMR, FTIR, elemental analysis and UV-Vis absorption and photoluminesence spectroscopy measurements, respectively. The investigations indicate that complexes 2-4 emit bright or- ange-red fluorescence and have intensely visible absorption in blue-purple region. Complexes 2-4 show the photophysics properties of high quantum efficiencies （φ）, long excited-state luminescence lifetime （r）, large Stocks shift （147-205 nm） and good oxygen-induced luminescence quenching properties （Ksv 〉/3.5, （I0/I）max≥4.0）. Among them, complex 3 grafted by an amino functional group has a Ф of 10%, a τ of 381.8 ns, a Ksv of 3.49 and the maximum I0/I factor of 4.33. However, complex 2 grafted by a bromine group shows higher Ф of 18%, longer luminescence r of 635 ns, larger Ksv of 4.59 and the maximum I0/I factor up to 5.29. These properties make it a promising fluorescence indicator applied in grafting and high perform-ance optics oxygen sensor.
