Enhanced TNT Vapor Detection via a Donor-Acceptor-Based Imine Cross-Conjugated Aggregation-Induced Enhanced Emission Active Porous Polymer.

ABSTRACT: The development of sensitive and selective probes for the detection of nitro explosives is critical for ensuring public safety and environmental monitoring. Among various detection strategies, porous materials offer significant advantages for vapor-phase detection due to their high surface area and analyte-trapping capability. In this study, we report the design and synthesis of an electron-rich system with a donor-acceptor (D-A)-based organic porous polymer (P1), incorporating triphenylamine as the electron-donating unit and imine-conjugated sulfone (SO₂) functionalities as electron acceptors. The resulting aggregation-induced enhanced emissive (AIEE) porous network exhibits selective fluorescence quenching in the presence of nitro explosives, particularly picric acid (PA) and
