Abstract:
The syntheses of 2,7-diamino-1,3,6,8-tetraazabenzopyrene framework was achieved through CuI-catalyzed double annulation of 1,4-diiodoanthraquinone with guanidine. In addition, the preparation of series of 2,7-disubstituted 1,3,6,8-tetraazabenzopyrenes functionalized by NR2, C=O, Cl, alkoxy and phenoxy groups with good yields was achieved through the simple transformations such as diazotization, alkylation and nucleophilic aromatic substitution. The properties of 1,3,6,8-tetraazabenzopyrenes synthesized were studied by DFT-calculations, optical and photoluminescence spectroscopy, cyclic voltammetry and light-induced EPR spectroscopy. The luminescence of amino derivatives is quenched in acidic solutions depending on the degree of protonation.
