The highly sensitive detection of carcinogenic pollutant 2,4,6-trinitrophenol (PA) is of great significance for environmental protection and human health. Based on the organic building block 1,3,6,8-tetrakis (p-benzoic acid) pyrene (H₄TBAPy), the porous nano-scale hydrogen-bonded organic framework material (PFC-1) was successfully synthesized. The large π-π conjugated structure makes it to show excellent fluorescence characteristics. PFC-1 showed excellent selective fluorescence detection for PA. PFC-1 exhibited significant quenching effect upon the addition of PA. The quenching efficiency Ksv of PFC-1 material for PA is 9.14×10⁴ M⁻¹ and the limit of detection (LOD) reaches 0.75 μM. PFC-1 exhibits excellent fluorescence sensing performance for PA, which greatly expands the potential application of hydrogen-bonded organic framework materials in the field of fluorescence sensing.
