Organometallic Intermediates in the Synthesis of Photoluminescent Zirconium and Hafnium Complexes with Pyridine Dipyrrolide Ligands.

ABSTRACT: The two commercially available zirconium complexes tetrakis(dimethylamido)zirconium, Zr(NMe₂)₄, and tetrabenzylzirconium, ZrBn₄, were investigated for their utility as starting materials in the synthesis of bis(pyridine dipyrrolide)zirconium photosensitizers, Zr(PDP)₂. Reaction with one equivalent of the ligand precursor 2,6-bis(5-methyl-3-phenyl-1H-pyrrol-2-yl)pyridine, H₂^MePDP^Ph, resulted in the isolation and structural characterization of the complexes (^MePDP^Ph)Zr(NMe₂)₂thf and (^MePDP^Ph)ZrBn₂, which could be converted to the desired photosensitizer Zr(^MePDP^Ph)₂ upon addition of a second equivalen
