Three-dimensional nanographene based on triptycene for detection of nitroaromatic explosives

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 Ksv of 1.8 × 104 M−1 and sensitivity of 2.4 ng/mm2, respectively.
