Synthesis and luminescent properties of br-substituted poiy(n-vinylcarbazoles).

The synthesis of the polymer group containing carbazole as an element of the structure that generates the electroluminescence was performed, Studies were focused on molecular and electronic structures and transport properties. The determined physical properties of the polymers suggest that the materials can be applied in optoelectronic devices. The studies concerning electrooptic properties, photoluminescent and electroluminescent spectrum for the LED-type structure were performed on the following polymers: PVK, P3BrVK and P3,6BrVK. Photoluminescent spectra in the temperature range 80–300 K were obtained. Halogens as electronegative atoms strongly influence the electron structure of a carbazole group modifying its UV spectrum, photoluminescence properties and the electroluminescence.
