ABSTRACT Small‐molecule‐based fluorescent probes have garnered significant attention because of their excellent optical properties. Among these, multi‐stimuli‐responsive molecular been rapidly developed for wide range applications. In this study, we designed a bifunctional probe based on three‐coordinate boron compounds to detect fluoride ions and 4‐nitrophenol. Two NB1 NB2 , containing B‐mesityl 2 acceptors (A) nitrogen‐containing aromatic donors (D), were confirmed via single‐crystal X‐ray diffraction. The donor–acceptor (D–A) structure substantial steric hindrance enable these exhibit efficient fluorescence emission in both liquid solid states. Leveraging the properties boron, two visible rapid response ions, with detection limits 0.41 μM 1.31 . mechanism was corroborated by 19 F NMR spectra. Moreover, owing D–A B–N unit, 4‐nitrophenol, resulting from interrupted charge transfer. These serve as outstanding bifunctionality, stability, high efficiency. Given growing demand probes, possess great potential future sensing
