one another form catalysts for the borylation of alkyl C–H bonds with widely varying activity. This phenomenon was investigated computationally, and it was discovered that the stabilizing interactions between the phenanthroline ligand and the boryl ligands attached to Ir in the transition state for C–H oxidative addition could account for the differences in the activity of the catalysts that possess similar

kinetics substitution with L-histidine, DNA binding experiments, and cell cytotoxicity studies verified our assumptions. Surprisingly, these complexes could also be potential cellular imaging probes via an unprecedented “off–on” light-switching mechanism of living cells, which was caused by the “HOMO–LUMO” distribution changes of Ru complexes after interaction with DNA. Accordingly, the reactivity and selectivity
