η2-Porphyrin Ru(II) π Complexes

摘要

Highly stable η2-porphyrin Ru(II) π complexes have been synthesized. The formation of the η2 π bond has been facilitated through π−π stacking interactions between the porphyrin and the planar ligand on Ru. π coordination of ruthenium to porphyrin results in dramatic changes in the aromaticity and electronic properties. These properties are controllable via fine-tuning of the ligand on ruthenium.
