Abstract:

The coordination of a modified rhodamine B (Rhod) to a bis-bipyridine ruthenium (ii) (Ru-bpy) phototrigger complex enables a photodissociation reaction at longer wavelengths through enhanced absorption of green light (532 nm). The very high molar absorptivity of rhodamine (∼105 M -1 cm-1) and the high quantum efficiency of Förster resonance energy transfer (FRET) from rhodamine to the Ru-bpy center (0.84) result in an unusually high photosensitivity and uncaging cross-section of the Ru-bpy-rhodamine complex at longer wavelengths. © The Royal Society of Chemistry and Owner Societies 2012.
