title: Excitation energy flow control in {Ru(2,2'-bipyridine)2}-{pyridylporphyrin}2 systems.
abstract: The direction of excitation energy migration is reversed in a system composed of {Ru(bpy)(2)}-{pyridylporphyrin}(2) by the addition of a Zn(2+) ion. The Zn(2+) system shows an excitation-wavelength dependent emission.
