摘要: Four three-dimensional (3D) pyrene-fused N-heteroacenes (P1-P4) are designed and synthesized. From P1 to P4, their lengths extended in an iterative way, where the thiadiazole unit can be reduced diamine obtained diamines further condensed with diketones a unit. Compared two-dimensional counterparts, solubility of these 3D is improved by this covalent linkage units. The diameters P1-P4 3.66, 6.06, 8.48 10.88 nm, respectively, molecules characterized 1H, 13C 2D NMR, MS, UV-vis, PL CV spectra. Our strategy shows promising way large N-heteroacenes.
