“…So far, paper-based optical chemical sensors for neutral molecules, anions and cations, relying on benzimidazole derivatives as recognition element, have been successfully presented by several research groups. For example, Boonsri et al demonstrated paper-based sensors for the trinitrotoluene (TNT) detection [74]. Sensing material prepared from pyrene-substituted benzimidazole-isoquinolinones can readily detect TNT in aqueous media by a naked-eye observation at concentrations as low as 50 μM.…”

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.

“…Nevertheless, the main limitation of colorimetry is low sensitivity and interference by the food sample matrix. Fluorescence detection achieves the quantification of the target by measuring the intensity of the light emitted after the fluorescent substance is irradiated by a laser with an appropriate wavelength . Nowadays, portable commercial detection equipment and mobile cameras can realize accurate fluorescence intensity analysis, making fluorescence detection more popular.…”

Food safety is an issue that cannot be ignored at any time because of the great impact of food contaminants on people's daily life, social production, and the economy. Because of the extensive demand for high-quality food, it is necessary to develop rapid, reliable, and efficient devices for food contaminant detection. Microfluidic paper-based analytical devices (μPADs) have been applied in a variety of detection fields owing to the advantages of low-cost, ease of handling, and portability. This review systematically discusses the latest progress of μPADs, including the fundamentals of fabrication as well as applications in the detection of chemical and biological hazards in foods, hoping to provide suitable screening strategies for contaminants in foods and accelerating the technology transformation of μPADs from the lab into the field.

“…Even after nearly four decades of its discovery, it is applied in pharmaceutical, sensors and polymer industry. [4][5][6] The reasons why this reaction enjoys overwhelming success as the key part of the modern chemistry toolbox include the ease with which organoboron reagents are crosscoupled with aryl or heteroaryl halides with high predictability, operational-simplicity, and tolerance for a large number of groups and substituents. [7] In addition, it also offers the advantages, which include: (i) easy availability of organoboron compounds which are thermally stable and inert to oxygen and many solvents including water; (ii) low toxicity of starting materials and by-products; (iii) relatively milder reaction conditions (iv) production of different aryl derivatives high yield and selectivity.…”

“…It has been studied more than Stille coupling, Heck coupling, Negishi coupling, Liebeskind‐Srogl coupling, Kharash coupling, Kumuda coupling and Himaya coupling. Even after nearly four decades of its discovery, it is applied in pharmaceutical, sensors and polymer industry [4–6] . The reasons why this reaction enjoys overwhelming success as the key part of the modern chemistry toolbox include the ease with which organoboron reagents are cross‐coupled with aryl or heteroaryl halides with high predictability, operational‐simplicity, and tolerance for a large number of groups and substituents [7] .…”

During last two decades, researchers have employed organochalcogen compounds as ligands for the development of pre‐formed chalcogen ligated molecular complexes. During 2013–2020, various chalcogen containing homogenous catalytic systems for Suzuki Miyaura cross‐coupling reaction have been synthesized. The review provides insights into the synthetic methodologies for the preparation of organochalcogen ligands and their transition metal complexes. Another central aspect discussed is the application of such catalytic systems in Suzuki Miyaura coupling. Rationalization about the effect of temperature, substrate scope, organoborane derivatives and aryl halides employed has been elaborated. Effect of binding mode, ligand framework, chalcogen donor atom, metal and many other aspects that influence the catalytic potential of various systems have also been covered. Various other aspects such as green catalysis, use of non‐conventional energy sources have also been analyzed.
