Abstract

This work reports a fluorescent porous organic cage (RCC7) with AIE characteristics, enabling highly sensitive detection of nitroaromatic explosives. The probe achieves a 2.14 ppb detection limit for picric acid through inner filtration, resonance energy transfer, and π–π interactions, and further demonstrates ambient visual detection using test strips.
