Energy transfer from a rhodamine antenna to a ruthenium-bipyridine center
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 hi...
