The synthesis of fluorescent organic nanoparticles (FONPs) with an imine‐linked 1,8‐naphthalimide‐based dipodal chemosensor for Ag I is described. The FONPs were prepared by using a re‐precipitation method, and they were successfully applied for the nanomolar detection of Ag I ions in aqueous media. More specifically, the chemosensor was utilized for the selective and ratiometric sensing of Ag I in a concentration range 15–65 n M with a 15.5 n M detection limit. The work was extended to monitor the Ag I concentration in samples of environmental importance.
