Abstract Herein we report design, synthesis, characterization and application of a series of molecules with D-π-A structures that contain a push-pull-pull with substituted carbazole as the electron donor and cyanoacrylic acid as the electron acceptor bridged by a benzothiadiazole fragment. Theoretical, electrochemical and photophysical properties of the target molecules with respect to the chemical nature and position of substituent on the carbazole moiety were investigated in detail. The substituents on carbazole changed the solubility, packing and orientation of molecules on the TiO 2 surface of DSSCs. The dye sensitized solar cell performances of the molecules were studied and compared with respect to the position and substituent.

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, respectively. The optical and electrochemical properties of these copolymers were measured and compared with those of poly(N-alkylcarbazole-alt-aniline) copolymer. All synthesized poly(N-arylcarbazole-alt-aniline) copolymers showed maximum UV-Vis absorption peaks at around 300 nm in THF solution, and exhibited maximum photoluminescence peaks in the blue emission range from 430 to 460 nm. It was also found that poly(N-arylcarbazole-alt-aniline) copolymers had wider band gap energy than poly(N-alkylcarbazole-alt-aniline) copolymer.
