Abstract
A new series of carbazole-pyridine copolymers containing 3,3′-bicarbazolyl moiety in the main chain have been synthesized and characterized. The polymers exhibit good solubility in common organic solvents as well as good thermal stability above 300°C and the glass transition temperature above 150°C indicating their expediency in the device fabrication. The photophysical properties divulge emission in the blue region from 402 to 442nm. All compounds have reversible oxidation and desirable ionization energy and electron affinity level owing to 3,3′-biscarbazole and pyridine moieties. These results signify prospective use of polymers as promising blue luminescent materials in optoelectronics applications.
