Abstract
The synthesis and characterization of zinc(II) chelates bearing acridin-4-ol (A), phenazin-1-ol (P), and benzo[b]phenazin-1-ol (bP) are presented. The formation of homoleptic (ZnX2) or heteroleptic (ZnX1) products can be controlled by stochiometric or excess amounts of zinc(II) acetylacetonate monohydrate, Zn(acac)2, respectively. Electrochemical and photophysical studies show that the homoleptic complexes (ZnA2, ZnP2, and ZnbP2) have ligand-centered properties inherited from the corresponding free ligands. Calculations using density functional theory (DFT) agree with the observed experimental ligand-centered photophysical and electrochemical behavior.
