Abstract
AbstractThe 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.
