Abstract

Small push-pull molecules were synthesized in high yields by connecting a N-methyl or N-phenyl substituted thieno[2,3-b]indole electron-donating block directly to a 2,2-dicyanovinyl or (1-(dicyanomethylene)-3-oxo-1-inden-2-ylidene)methyl electron-withdrawing group. The effects of the N-substitution on thieno[2,3-b]indole and the nature of the electron-accepting group on the electrochemical, optical, and charge-transport properties were investigated by cyclic voltammetry, UV-vis spectroscopy, and the space-charge-limited current method, respectively. These results, together with the 1% power conversion efficiency of a bilayer solar cell prepared with the smallest compound of the series, show the potential of thieno[2,3-b]indole for organic electronics.
