Abstract

Thermally stable and solution-processable poly (N-arylcarbazole-alt-aniline) copolymers with high structural integrity were synthesized in good yields via palladium-catalyzed polycondensation of aniline with corresponding N-arylcarbazole monomers such as N-(2- ethylhexyloxyphenyl)-3, 6-dibromocarbazole, bis [6-bromo-N-(2-ethylhexyloxyphenyl) carbazole-3-yl] and N-(4-(2-ethylhexyl)-3, 5-dibromomethylene-phenyl) carbazole, ...
