A significant fluorescence quenching of DHN at 535 nm was observed upon interaction with both PA and OCl? with the detection limits at 0.012 ?M and 2.34 ?M as well as high quenching efficiencies (Ksv) of 3.811 104 M?1 and 1.164 104 M?1, respectively. To elucidate the sensing behavior, various spectroscopic techniques were employed. Interestingly, DHN exhibited AIE behavior in high water content, showing a red-shifted emission accompanied by a visible fluorescence change from whitish green to yellow. As a novel application, DHN was incorporated into a 3D-printed polymer system, demonstrating its practical utility in detecting PA and OCl?. Further, for biological relevance, the interaction of DHN with OCl? was explored for its cytotoxicity against MCF-7 breast cancer cells and its imaging capability in physiological media. Therefore, we believe that the present work provides a promising direction for the future development of optical-based detection of hypochlorite and picric acid in liquid as well as solid phases. 2026 Wiley-VCH GmbH.
