Abstract:
A comprehensive understanding of how the molecular structure influences the electronic coupling is crucial in optimizing (supra) molecular assemblies for photoinduced electron transfer. Here, we report that the electronic coupling underlying electron transfer from a phenothiazine donor to a photoexcited Ru(tpy)₂ acceptor is modulated by substitution of the second (remote) tpy-ligand.
