Abstract
Highly stable eta2-porphyrin Ru pi-complexes have been synthesized. The formation of the eta2-pi-bond has been facilitated through pi-pi stacking interaction between the porphyrin and the planar ligand on Ru. pi-Coordination of ruthenium to porphyrin results in dramatic changes in aromaticity and electronic properties. These properties are controllable via a fine-tuning of a ligand on ruthenium.
