In vitro and in vivo biological effects of novel arylimidamide derivatives against Trypanosoma cruzi

Chagas disease (CD), a neglected tropical disease caused by Trypanosoma cruzi, remains a serious public health problem in several Latin American countries. The available chemotherapies for CD have limited efficacy and exhibit undesirable side effects. Aro

A new multi-electrochromic 2,7 linked polycarbazole derivative: Effect of the nitro subunit

A new poly-2,7-di-2-thienyl-9H-carbazole derivative (poly(TCT-N)) bearing nitro (-NO2) subunit has been reported. The electrochemical and optical properties of TCT-N monomer and its polymer have been compared to the 9-phenyl-2,7-di-2-thienyl-9H-carbazole (TCT) standard molecule. Cyclic voltammetry revealed that TCT-N and TCT have excellent polymerization activity; due to extended conjugation with the attached thiophene unit and also their low oxidation potentials. The oxidation potential of TCT-N is higher than that of TCT, because of electro-withdrawing effect of -NO2 moiety. Besides, the TCT-N polymeric film prepared via electrochemical process exhibits a multi-electrochromic behavior compared with TCT standard molecule. The electroactive orange color of poly-TCT-N film converted respectively to green, turquoise and dark blue upon applied positive potentials. Consequently, the polymeric electrochrome exhibits multi-electrochromic behavior, high redox stability, high coloration efficiency and reasonable response time for electrochromic applications.

Novel fluorescent carbazolyl-pyridinyl alternating copoloymers: Synthesis, characterization, and properties

A novel series of AB-type polymers comprised of alternating carbazolyl and pyridinyl units were synthesized using palladium(0)-catalyzed Suzuki cross-coupling reaction in good to high yields. In this series of alternating copolymers, the electron-rich 2,7-(N-(2-ethylhexyl)carbazolyl) unit was used as a light-emitting unit, and the electron-deficient unit of pyridinyl was introduced to tune the wavelength of the emitting light and improve their electron transportation. These polymers were characterized by 1H NMR and 13C NMR, gel permeation chromatography (GPC), thermal analysis, UV-vis, fluorescence spectroscopy, and cyclic voltammetry (CV). The glass transition temperature of these polymers ranged from 120 to 150°C, and the polymers showed high thermal stability with decomposition temperatures in the range 370-400°C in nitrogen. The different linkage pattern of pyridinyl units in the copolymer backbone has a significant effect on the electronic and optical properties in solution and in film phases. For pure blue emission and prevention of aggregation of polymer chain, the meta-linkage pattern (3,5-and 2,6-linkage) of pyridinyl units in the polymer backbone is more favorable than the para-linkage pattern (2,5-linkage) of the pyridinyl units. The cyclic voltammetry (CV) results indicate that these polymers with pyridinyl units possess lower LUMO energy levels for an easy electron injection from a cathode than poly[3,6-(N-octyl)carbazolyl] and its derivatives do.
