Carbazoles cyanoacrylate sensitizer

A study on the influence of the aggregation of a carbazole cyanoacrylate sensitizer on sensitized photocurrents on single crystals was carried out (13T9362). AFM imaging showed the formation of larger aggregates (max size 20-30 nm) from mixtures in water/THF solutions, compared with 8-12 nm in pure THF In addition, the presence of aggregation in solution due to water was confirmed by absorbance and fluorescence spectroscopy. 

Recently, D-A-based ter- and quaterthiophenes 2.82 (w = 1, 2) (Chart 1.18) endowed with A-ethylcarbazole and cyanoacrylic acid at each terminus were prepared for their utilization as the active component in dye-sensitized solar cells (DSSCs) [163]. Coupling of the Grignard reagent of 2-bromo-3-hexylthiophene and 3-iodo-9-A-ethylcarbazole yielded carbazole-substituted thiophene.
