Electron donor–acceptor (EDA) complexes are characterized by charge-transfer (CT) processes between electron-rich and electron-poor counterparts, typically resulting in a new absorption band at higher wavelength. In this paper, we report series of novel 2,6-di(imino)pyridine ligands with different aromatic substituents their 1:2 (metal/ligand) zinc(II) which the formation CT species is promoted...
