Abstract
Well defined carbazol-3,9-diyl-based oligomers of new type have been synthesized by the modified Ullmann reaction starting from 3-iodo-9H-carbazole and diphenylamine. The full characterization of their structure is presented. The amorphous compounds with glass transition temperatures of 111-162 °C possess high thermal stability with onset decomposition temperatures of 320-380 °C. Amorphous films of the materials were fabricated by vacuum evaporation. They were used for the preparation of multilayer electroluminescent devices.
