Catalyzing Singlet Fission by Transition Metals: Second versus Third Row Effects.

ABSTRACT: The synthesis and characterization of platinum(II) and palladium(II) complexes bearing two (dimers Pt(L_pc)₂Cl₂ and Pd(L_pc)₂Cl₂), one (monomers Pt(L_pc)(L_ref)Cl₂ and Pd(L_pc)(L_ref)Cl₂), or no (reference compounds Pt(L_ref)₂Cl₂ and Pd(L_ref)₂Cl₂) pentacene-based pyridyl ligands are presented. Photophysical properties of the dimers are probed by means of steady-state and time-resolved transient absorption measurements in comparison to the monomer and model compounds. Our results document that despite enhanced spin-orbit coupling from the presence of heavy atoms, intramolecular singlet fission (iSF) is
