Intermolecular energy-transfer dynamics in {Delta-[Ru(bpy)(3)]}{Lambda-[Os(bpy)(3)]}(PF6)(4) and rac-[Os(bpy)(3)](PF6)(2) crystals

摘要

In the crystal composed of Delta-[Ru(bpy)(3)](2+) and Lambda-[Os(bpy)(3)](2+) complexes which were pseudo enantiomers the photo-excitation energy was effectively transferred from [Ru(bpy)(3)](2+) to [Os(bpy)(3)](2+) (k(ET) > 1.1x10(8) s(-1)). In rac-[Os(bpy)(3)](PF6)(2) crystal the energy-transfer rates from Lambda-[Os(bpy)(3)](2+) to Lambda-[Os(bpy)(3)](2+). and from Lambda-[Os(bpy)(3)](2+) to Delta-[OS(bpy)(3)](2+) were estimated as k(perpendicular to) = 1.8x10(6) s(-1) and k(H) = 7.9x10(5) s(-1), respectively.
