By the Ullmann reaction between carbazole and bromo- or iodine-substituted functionalized 1,2,3-triazole reagents 17 new donor-acceptor materials were synthesized in which the donor (carbazol) fragment was attached via the π-bridges to the acceptor – 1,2,3-triazole unit in all possible variations. For the synthesized compounds photophysical studies were performed. Two compounds were used in the construction of non-doped OLED devices with turquoise and yellow-green electroluminescence.
