Abstract

A novel series of AB-type polymers comprised of alternating carbazolyl and pyridinyl units were synthesized using palladium (0)-catalyzed Suzuki cross-coupling reaction in good to high yields. In this series of alternating copolymers, the electron-rich 2, 7-(N-(2-ethylhexyl) carbazolyl) unit was used as a light-emitting unit, and the electron-deficient unit of pyridinyl was introduced to tune the wavelength of the emitting light and improve their electron ...
