Summary:Abstract Hydrogen‐bonded organic frameworks (HOFs) represent an emerging class of porous crystalline materials, have attracted growing interest in the field of fluorescence sensing area due to their distinctive luminescent characteristics, large surface area and abundant recognition sites. Herein, the porous material HOF‐BTB‐NH 2 featuring one‐dimensional pore structure was successfully synthesized through hydrogen‐bonding self‐assembly using the organic building molecule 2,4,6‐Tris(4‐carboxyphenyl)aniline (BTB‐NH 2 ) in methanol. HOF‐BTB‐NH 2 showed excellent sensitivity and selectivity for metal ion Cu 2+ and anion CO 3 2− , and the limits of detection (LOD) reached 0.23 μM and 0.33 μM, respectively. In addition, HOF‐BTB‐NH 2 was employed as a biosensing material for the highly selective and sensitive detection of dopamine (DA). The synthesis of porous HOF‐BTB‐NH 2 and the excellent sensing performance greatly expanded the application of hydrogen‐bonded organic framework materials in fluorescence sensing.
