Abstract: New unsymmetrically substituted benzothiadiazoles were synthesized from 4,7-dibromo-2,1,3-benzothiadiazole via the sequence of Pd-catalyzed Suzuki and Buchwald–Hartwig cross-coupling reactions with 4-methoxyphenylboronic acid and heterocyclic amines, respectively. Based on initially performed photophysical study as well as DFT calculation, these compounds, in particular with dibenzoazepine core, can be selected as promising scaffolds for further fine-tuning of their properties to be used in optoelectronics including OLED technologies.

Keywords: benzothiadiazoles, luminophores, cross-coupling, synthesis, photophysical properties.
