【 摘 要 】

Intervalence charge transfer properties were studied for a set of mixed valence complexes incorporating Ru(III) and Fe(II)-centres linked by various saturated and unsaturated bridging ligands (BL). Studies reveal that degree of ground state electronic interaction and coupling between Ru(III) and Fe(II)-centres can be attenuated by changing the nature of the bridging ligand. Further, inclusion of the bridging ligand with interrupted 𝜙-electron system in a 𝛽-CD cavity initiate an optical electron transfer from Fe(II) to Ru(III) which is otherwise not observed.
