Abstract

The emission spectra of Ru(bipy)2 (dppx)2+ in different environments has been studied. It was found that the solvent polarity and the ability of donating and transferring proton are the important factors in predicting luminescence intensity in different systems. The increasing content of water in the organic solutions of Ru(bipy)2 (dppx)2+ leads to decrease in emission intensity that follows the Perrin sphere of quenching model. The effect of base content of DNA on the fluorescence spectra of Ru (bipy)2 (dppx)2+ has also been studied.
