Donor–acceptor (E)-2-[2-(2,2′-bithiophen-5-yl)vinyl]benzo[d]thiazole: synthesis, optical, electrochemical studies and charge transport characteristics

Condensation of 2-methylbenzothiazole with 2,2′-bithiophene-5-carbaldehyde affords the title compound, a new chromophore. This compound was used for the doping of poly[9,9-bis(6-diethoxylphosphorylhexyl)fluorene], and the obtained composites demonstrated high electron mobility (1.50 × 10−4 cm2 V−1 s−1) in contrast to dopant-free matrixes.
