Abstract

Deoxyribonucleic acid (DNA)-based functional materials containing luminescent molecules have attracted widespread attention as opto-electronic materials. In this study, luminescence properties of DNA/chiral Ru(phen)3^2 + complexes were investigated. The DNA/chiral Ru(phen)3^2 + complexes showed an enantioselective enhancement of luminescence. The DNA / Δ-Ru(phen)3^2 + complex showed a higher luminescence intensity and longer luminescence lifetime than the DNA / Λ-Ru(phen)3^2 + complex. Binding modes between DNA and Δ- / Λ-Ru(phen)3^2 + are discussed in terms of optical properties. The study shows that Δ-Ru(phen)3^2 + preferentially intercalates to form a more stable DNA complex than Λ-Ru(phen)3^2 +, leading to enantioselective luminescence enhancement.
