Abstract
In order to find proper materials for making electroluminescent diodes electrooptics properties of polymers were investigated. Three polymer groups based on carbazole molecule were the subjects of the studies: PVK modified by substituting the acceptor group or donor group in the carbazole ring, poly-ω-(9-carbazolyl)alkyl methacrylates and copolimer ω-(9-carbazolyl)alkyl - methacrylates with 3-(2-metakryletoxy)carbonyl 7 diethylamincoumarin. Absorption and photoluminescent spectra of polymer in solution and films were measured. Electroluminescent diodes were obtained using the polymers mentioned above. Also, hole mobility was measured according to the distance between the carbazole group and the main chain.
