Abstract

The preparation and characterization of poly[(3,6-difluoro-9-(1-heptadecan-9-yl)-9H-carbazole-2,7-diyl)-alt-(2,3,7,8-tetraphenyl-10-(thiophen-2-yl)pyrazino[2,3-g]quinoxaline)-5,5’-diyl] P1 and Poly[(3,6-difluoro-9-(1-heptadecan-9-yl)-9H-carbazole-2,7-diyl)-alt-(2,3-diphenyl-8-(thiophen-2-yl)quinoxalin -5-yl)thiophen-2-yl)-5.5’-diyl] P2 are presented. The polymers were prepared via Suzuki cross-coupling reactions; both polymers provided low-band-gap polymers that absorbs light up to 350 nm of the electromagnetic spectrum. Cyclic voltammetry studies on the two polymers indicate greater electrolytic stability of these new polymers as compared to the polyfluorene equivalent [1,2]. Electrochemical and optical absorption show that the band gaps of P1 and P2 range from 1.64 and 1.93 eV.
