A new ligand, 2-phenyl(5-fluoro)imidazo[f]-1,10-phenanthroline (PIP(V)), and its coordination compounds, Ru(bpy)2PIP(V), were synthesized. The fluorescence spectrum of the interaction between Ru(bpy)2PIP(V) and DNA was studied, and a very strong fluorescence peak at a wavelength of 589 nm appeared. The optimum condition of analyzing DNA was decided. The method is simple, convenient and fast, and also has high sensitivity and good selectivity. It has been satisfactorily employed for determinations in synthesized samples.
