Fluorescent ligands and energy transfer in photoactive ruthenium-bipyridine complexes
Ruthenium bis(bipyridine) complexes have proved to be useful as phototriggers for visible and IR-light photodelivery of molecules. They usually expel one ligand heterolytically upon absorption of blue or green light. However, their absorption capabilities at wavelengths longer than 500 nm are poor....
