Abstract

(Chemical Equation Presented) the amide-amine, 1,1′- di(aminoethylaminocarbonylethyl)-2,2′-biimidazole (DAEPB) (1), and subsequent Schiff base imine product, 1,1′- di(salicylaldiminoethylaminocarbonylethyl)-2,2′-biimidazole (DSEB) (2a), have been synthesized from the ester, 1,1′-di(ethoxycarbonylethyl)-2, 2′-biimidazole (DEPB). Additionally, 1,1′- di(salicylaldiminoethylaminocarbonylmethyl)-2,2′-biimidazole (DSMB) (2b), was prepared from its corresponding amide-amine. All compounds were characterized with FTIR, NMR and elemental analyses. the salicylaldimines, compounds (2a) and (2b), exhibit fluorescence at 540 and 520 nm, respectively, over a broad range of excitation wavelengths.
