| Abstract [eng] |
The use of charge transporting materials in optoelectronics has increased significantly over the past years. Organic semiconductors and other electroactive materials are superior to their inorganic analogues because of their high diversity, low cost and the possibility of forming their layers using the cheap spin coating method. By connecting various functional fragments to already known compounds, new compounds with better chemical and physical properties can be obtained. These materials are used in many areas: electro-photographic photoreceptors, organic light-emitting diodes, organic transistors, solar cells, etc. Materials used in these areas should be characterized by a high level of charge drift mobility in their layers, good film-forming properties, morphological and thermal stability. However, there is still a lack of organic semiconductors that are characterized by the optimal combination of the afore-mentioned properties. New (di)phenylethenyl-substituted derivatives of azoles, phenoxazine and diphenylamine were synthesized, characterized and are described in this dissertation. These compounds were effective hole-transporting materials and were used in phosphorescent or fluorescent organic light emitting diodes. In addition, new low-molar-mass compounds, containing electronically isolated carbazole or triphenylamine fragments were synthesized and characterized. They were effective host materials for emitting layers of electrophosphorescent organic light emitting diodes. |
