Annotation:

In this work several series of new donor-acceptor organic materials were designed, synthesized and investigated. Carbazole-chloropyridine luminophores were obtained by simple one-step synthetic process and showed delayed fluorescence properties. New thiazolo-oxadiazaborinine complexes demonstrated high photoluminescence quantum yield and short fluorescence lifetimes. Through-space charge transfer phenomenon was studied for the carbazole-based aromatic imides. Photophysical, thermal and electrochemical properties for the selected materials were investigated. Additionally, phthalimide-carbazole derivative were used in the fabrication of doped and non-doped OLEDs, reaching 2.4% of maximum external quantum efficiency and 8300 cd/m² of maximum brightness.
