Vintu, M. published the artcileIndolo[3,2-b]carbazole-based poly(arylene ethynylene)s through Sonogashira coupling for optoelectronic and sensing applications, Formula: C18H10, the publication is Journal of Applied Polymer Science (2019), 136(2), n/a, database is CAplus.
Two indolo[3,2-b]carbazole (ICZ)-based polymers were designed and synthesized using Sonogashira cross-coupling based on dibromoindolo[3,2-b]carbazoles and 2,7-diethynylfluorene or 9,10-diethynylanthracene. The 2, 8 positions of the ICZ moiety was used for the bridging of arylene ethynylene structure to form the polymer backbone. The characterization was done by FTIR, 1H NMR, UV-visible and (UV-visible) fluorescence spectroscopic methods. The polymers, moderately soluble in aprotic and chlorinated solvents, possess thermal stability >300°. The band gap examinations, executed through cyclic voltammetry and complemented by UV-visible studies, indicated their semiconducting nature and the possibility for their use for the fabrication of polymer solar cells and for optical switching applications. The new diethynylindolocarbazole systems act as Broensted acid sensors as well as a Hg2+ receptors. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46940.
