Redox-activated luminescence and light-induced nuclease activity of a new mixed-ligand ruthenium(II) complex

摘要

The new metallointercalator 1, a mixed-ligand ruthenium(II) complex incorporating a quinone-fused dipyridophenazine ligand, effects an efficient cleavage of the supercoiled plasmid DNA upon activation with visible light. In addition, the quinone/hydroquinone redox couple 1/2 represents a molecular light-switching device displaying interconversion between non-luminescent state 1 and luminescent state 2.
