Abstract

Two new bichromophoric ruthenium(II) complexes, [Ru(bpy)2(bpy-CM)](PF6)2 and [Ru(bpy)2(bpy-CM343)](PF6)2 (bpy=2,2′-bipyridine, CM=coumarin) with appended coumarin ligands have been designed and synthesized. The energy-transfer-based sensing of esterase by the complexes has been studied by using UV/Vis and luminescence spectroscopic methods. The cytotoxicity and the cellular uptake of one of the complexes have also been investigated.
