Abstract

A new cydometalating bridging ligand 1,3,6,8-tetra(2-pyridyl)pyrene was designed acid synthesized through 4-told Suzuki couplings between 1,3,68-tetrabromopyrene and 2-pyridylboronate. A bis-cyclometalated bisruthenium complex bridged by this ligand showed the presence of an electronic coupling between individual metal centers, as indicated by electrochemical and spectroscopic studies.
