Synthesis of new asymmetric poly-π-conjugated 1-substituted derivaties of 5,5-dioxodibenzothiophene containing 1,2,3-oxadiazole fragment in the main chain of conjugation and cyclic fragments as the central chromophore are synthesized. The preparative yield of the target compounds was achieved using phosphorus (V) oxychloride as a cyclizing agent. The compounds obtained have high melting points and are blue phosphorescent luminophores.
