Synthesis, electroluminescence, and photovoltaic cells of new vinylene-copolymers with 4-(Anthracene-10-yl)-2,6-diphenylpyridine segments

Abstract

Three new soluble vinylene-copolymers F, C, and P that contain 4-(anthracene-10-yl)-2,6-diphenylpyridine as common segment and fluorene, carbazole, or phenylene, respectively, as alternating segment were prepared by Heck coupling. The glass transition temperature was high for F and C (110 and 117°C), whereas was lower than 25°C for P. The polymers were stable up to ∼ 300°C. They emitted blue-green light with maximum located at wavelength of 456-550 nm, which was of the order F < C
