“…It was found that Ca 2+ (FE = 3), and Ba 2+ (FE = 9.4) cations induced the strongest increase in fluorescence, while no optical changes was observed for other metal cations. [ 89 ] A fluorescence increase was also observed for polymer P16‐HG but to a slightly lower degree: Ca 2+ (FE = 2.3) and Ba 2+ (FE = 4.8). The difference in the sensing properties of monomer 16 and the gel was explained by the competition of dimethylcarbamido groups with crown ether for the formation of coordination with cations and coulomb repulsion of positively charged metal cations.…”

The beginning of the 21st century was marked by the intensive development of fiber‐optic sensors. New functional materials with excellent sensory properties are required to design such sensors. Fluorescent probes for neutral and charged molecules are constantly developing. However, only a small part of the reported probes was successfully converted into functional sensing polymers and found real‐world applications. A great challenge is to retain the sensing properties of a probe in a polymer matrix. The purpose of this review is to understand how properties of a probe are changed upon incorporation into a polymer and to reveal successful approaches. The review focuses on the use of the naphthalimide‐based probes in the construction of sensing polymers. The literature overview is presented according to the nature of the guest molecules targeted for the quantitative detection: cations, anions, and small organic molecules.
