Synthesis and study of charge-transfer complexes for 5,6- dimethyl-2,1,3-benzoselenadiazole

Abstract

THE SYNTHESIS.of new solid charge - transfer (CT) complexes using 5,6-dimethyl-2,l,3-benzosclnadiazoles as donors with 1,4naphthaquinone; 1,8-dihydroxy anthraquinone, 2-hydroxy-l,4naphthaquinone and 2,3-dichloro-4,5-dicyano p-benzoquinone (DDQ) as acceptor to obtain compounds I-IV, respectively are reported. These complexes are characterized by elemental analysis, IR, UV-Vis electronic, 1HNMR and ESR spectroscopic data. The conductivity for the solid complexes I-IV reveals that they are not conductors.
