Abstract
Heteroaromatics-containing polymers comprise a huge class of materials that have received considerable attention due to their interesting electrical, electrochemical and optical properties. In this review, the recent advances on the use of cross-coupling reactions for the synthesis of heteroaromatic, conjugated monomers and polymers for the optoelectronic interests and applications are summarized. This review article focuses on synthesis, polymerization, structures, properties and application of crowded symmetric arylenes, which are of interest because of their viewpoint as material for environmental devices. Synthesis of the symmetric heteroarylenes was provided due to Suzuki and Stille coupling. Polymerization was mostly processed as two steps two-electron oxidation of molecules. In single-electron oxidation, stable radical cation is formed with spin located on main unit of structure. The electrochemical properties of polymer are dependent on film thickness deposited on electrode. Analysis of polymer behavior and results of spectrochemical measurements of obtained derivatives point to mixed type of electroconductivity of material.
Keywords: cross-coupling, heterocycles, palladium, stille reaction, Suzuki coupling, LB films, cyclic voltammetry, electropolymerization, polymerization, fluorescence, theoretical study

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
