Targeted synthesis of core–shell porous aromatic frameworks for selective detection of nitro aromatic explosives via fluorescence two-dimensional response

Abstract

A series of core–shell porous aromatic frameworks (PAFs) are synthesized for selective detection of nitro-explosives. The conjugated core–shell PAFs possess large surface areas, which can facilitate the pre-concentration of a targeted analyte, leading to superior sensitivity. The tunable LUMO energy levels of these core–shell PAFs make them selectively detect high explosive TNT and TNP from other competing nitro compounds. Moreover, vapor phase detection of nitro aromatics using PPC-PPyS-PAF-2 exhibits a two dimensional fluorescence signal response toward different nitro aromatics. The power to accurately recognize nitro aromatic explosives in the fluorescent 2D map highlights the core–shell PAFs as very promising materials for nitro explosive sensing.
