Abstract: High Resolution Image Download MS PowerPoint Slide A new triazine containing pyridinium organic polymer ( TB-Py-COP ) based on 4-amino-1,8-naphthalimide Tröger’s base is developed and employed as a fluorescent chemosensor for selective sensing of organoarsenic feed additives in water. TB-Py-COP was readily synthesized by reacting “V-shaped” bis-[ N -(4-pyridyl)methyl)]-9,18-methano-1,8-naphthalimide-[ b,f ][1,5]diazocine with cyanuric chloride in DMF at 100 °C for 3 days. TB-Py-COP exhibited a strong fluorescence emission in water and displayed selective, reversible fluorescence sensing responses for the roxarsone feed additive at the nanomolar (19 nM) level of sensitivity. The Stern–Volmer quenching constant ( K SV ) was determined to be 1.4 × 10 4 M –1 . The selective sensing of roxarsone was further demonstrated in competitive environments, lake water, and buffer solutions.
