Enantioselective luminescence quenching of DNA light-switch [Ru(phen)(sub 2)dppz](Super 2plus) by electron transfer to structural homologue [Ru(phendione)(sub 2)dppz](Super 2plus)
Article Abstract:
The quenching of the luminescence of [Ru(phen)(sub 2)dppz](super 2plus) by structural homologue [Ru(phendione)(sub 2)dppz](super 2plus), when both complexes were bound to DNA, was studied for all four combinations of DELTA and LAMDA enantiomers. The lifetime of excited DELTA- [Ru(phen)(sub 2)dppz](super 2plus) is decreased, from 664 to 427 ns, when bound simultaneously with the phendione complex to DNA.

Monitoring the DNA binding kinetics of a binuclear ruthenium complex by energy transfer: Evidence for slow shuffling
Article Abstract:
The rearrangement of the ruthenium complex on DNA in real time is studied by analyzing the energy transfer from a minor groove binding dye DAPI. The analysis has shown that there is a slow cooperative effect and the ruthenium complexes move from a spread out binding during the intercalation toward the thermodynamically favored distribution.
