Design and synthesis of extended quinoxaline derivatives and their charge transport properties

A scalable and convenient strategy is described to synthesize extended conjugation quinoxaline derivatives from phenylene-ethynylene arrays. By tuning the solvent, the compounds display bright emission solvatochromism. Furthermore, the fabricated FET devices possess good performance characteristics, with mobilities of 0.47 cm2 V-1 s-1 and 0.99 cm2 V-1 s-1. The mobilities are higher than those of corresponding to the alkyl substituted compounds, which can be proven by grazing incidence X-ray diffraction (GIXRD) measurement.

NEW APPROACHES TO THE SYNTHESIS OF 4,4'-BIS(PHENYLGLYOXALOYL)BENZIL USING OXIDIZING REAGENTS BASED ON DMSO

Two new approaches were developed to the synthesis of 4,4'-bis(phenylglyoxaloyl)benzil, involving a combination of styrylation and ethynylation of substituted bromo- and iodoarenes and oxidation of the intermediate products with HBr/DMSO and I2/DMSO.
