Synthesis and Characterization of New D-π-D Type Schiff Base Ligands

Abstract

Two new Schiff bases with D-pi-D type have been successfully synthesized using the reaction of 3,3'-dimethylnapthide and 3,3',5,5'-tetramethylbenzidine with 4-(dimethylamino)cinnamaldehyde. The Schiff base ligands L-1 and L-2 have been characterized by IR, UV-visible, H-1 NMR and fluorescence spectra, as well as TGA-DSC-DTG, elemental analyses and mass spectra.
