3D nanographene 1, with three HBC units arraying in the 3D triptycene scaffold, displayed strong intrinsic fluorescence properties and could be used as a detector for nitroaromatic explosives such as TNP with quenching efficiency K sv of 1.8×10 4 M −1 and sensitivity of 2.4ng/mm 2 , respectively.
A series of Hexa-peri-hexabenzocoronene-based triptycenes bearing mono-, di-, or tri-HBC moieties were synthesized from iodotriptycenes. Their structures were determined by NMR, MS spectra, and X-ray analysis. The planar HBC moieties displayed strong deshielding effect to triptycene scaffold, resulting in significant downfield chemical shift of the two methenyl protons. Moreover, the HBC units are...
