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)32  +   complexes were investigated. The DNA/chiral Ru(phen)32  +   complexes showed an enantioselective enhancement of luminescence. The DNA  /  Δ-Ru(phen)32  +   complex showed a higher luminescence intensity and longer luminescence lifetime than the DNA  /  Λ-Ru(phen)32  +   complex. Binding modes between DNA and Δ-  /  Λ-Ru(phen)32  +   are discussed in terms of optical properties. The study shows that Δ-Ru(phen)32  +   preferentially intercalates to form a more stable DNA complex than Λ-Ru(phen)32  +  , leading to enantioselective luminescence enhancement.
