“…As an alternative to dye-impregnation of polymers, fluorescent molecules can be covalently attached to polymeric materials, as demonstrated, for example, in a fluorescence solid sensor for the mercury detection based on a photocrosslinked membrane functionalised with (benzimidazolyl)methyl-piperazine derivative of 1,8-naphthalimide [22]. Benzimidazole, linked to a piperazine moiety by a methylene spacer, is responsible for the specific recognition of Hg 2+ ions by forming a stable complex structure, that resulted in a strong fluorescence ( Figure 1B).…”

Benzimidazole derivatives are well-known biologically active substances, and therefore, they are mostly synthesised for therapeutic purposes. However, such heteroaromatic molecular systems own structure-related properties that enable a variety of applications, especially in optical science. Multifunctionality of the benzimidazole unit, such as electron accepting ability, π-bridging, chromogenic pH sensitivity/switching and metal-ion chelating properties, makes it an exceptional structural candidate for the design of optical chemical sensors and functional materials. Development of smart molecular sensors and novel (nano)materials is the emerging trend observed in materials and optical sensing science in general, in which the benzimidazole molecular systems strongly contribute and participate. In this chapter, we summarised recent advances in optical sensing (nano)materials that incorporate the benzimidazole structural moiety. Solid-state optical sensing systems, including self-assembled molecular materials based on benzimidazoles, are reviewed and discussed. In addition, immobilisation of benzimidazole derivatives onto or into various substrates and matrices, such as organic and inorganic polymers, bulk membranes and nanoparticles, utilising different chemical and physical methods, is presented and analysed.

“…A selective fluorescence sensor P14‐M was developed by grafting naphthalimide derivative 14 to a photocrosslinked membrane reaction through the acid chloride groups. [ 84 ] The resulting fluorescence sensor demonstrated 3‐fold fluorescence enhancement upon Hg 2+ binding in pure water at pH 5.5–8.0 (Figure 6). The selectivity for Hg 2+ was explained by the coordination of the metal cation to the (benzimidazolyl)methyl‐piperazine subunit, which in turn prohibits the PET process from the piperazine to naphthalimide.…”

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.

Organic fluorescent polymers have unique characteristics of fluorescent signal amplification and good optical properties, and can detect specific analytical species. Their sensing performance can be further improved through reasonable modification of their side chains. Nowadays, the organic fluorescent polymers are mainly prepared by metal coupling reactions, and there are also some syntheses involving in addition polymerization and condensation reactions. Taking the fluorescent source of these polymers as the main line, the research progress of the fluorescent organic polymers in the sensor field in recent years is systematically reviewed from the perspective of the type of reaction, especially their design and synthesis, sensing application, detection mechanism are summarized. In the future, it is still to be further investigated to design and synthesize novel multifunctional organic polymer fluorescence sensors as the key development direction.
