A series of 2,2'-dipyrrole monomers separated by aza-spacers (N,N'-bis-(1H-pyrrol-2-ylmethylene)-benzene-1,4-diamine; N-4,N-4'-bis(1H-pyrrol-2-ylmethylene)-biphenyl-4,4'-diamine; N,N'-bis-[1-(1H-pyrrol-2-yl)-ethylidene]-hydrazine; and 4,4'-bis[(1H-pyrrol-2-yl)-diazenyl] biphenyl) have been synthesised using modified Schiff and azo-coupling reactions. The new 2,2'-dipyrroles linked with conjugated aza-spacers have been evaluated as precursors of narrow band gap conducting polymers. Electrochemically synthesized poly(N,N'-bis-[1-(1H-pyrrol-2-yl)ethylidene]-hydrazine) displays a narrow band gap of just 0.7 eV, making it a suitable candidate for optoelectronic applications.
