    (Addis Ababa University, 2008-07) Tedla, Abebe; Mammo, Wendimagegn (Professor)
    2,3-Bis(4-(hexyloxy)phenyl)-5,8-di(thiophene-2-yl)quinoxaline synthesized by the condensation reaction between has been 1,2-bis(4- (hexyloxy)phenyl)ethane-1,2-dione and 3,6-di(thiophen-2-yl)benzene-1,2- diamine. This monomer has been characterized based on its 1 H-NMR, C-NMR and IR spectra. Syntheses of benzimidazole-based monomers 13 were attempted by the reaction between o-phenylenediamine and heptanal
