“…Toxic mercury cations were detected with sugar-based crown ether 183 (Figure ) by a large mercury-induced emission increase, leading to a detection limit of 12.6 μM . The fluorescent pyrene appendages were initially minimally fluorescent due to PET from the nitrogen atoms; however, they became strongly fluorescent upon mercury-induced disruption of PET.…”

There is great need for stand-alone luminescence-based chemosensors that exemplify selectivity, sensitivity, and applicability and that overcome the challenges that arise from complex, real-world media. Discussed herein are recent developments toward these goals in the field of supramolecular luminescent chemosensors, including macrocycles, polymers, and nanomaterials. Specific focus is placed on the development of new macrocycle hosts since 2010, coupled with considerations of the underlying principles of supramolecular chemistry as well as analytes of interest and common luminophores. State-of-the-art developments in the fields of polymer and nanomaterial sensors are also examined, and some remaining unsolved challenges in the area of chemosensors are discussed. CONTENTS 4.4.

“…LODs were found to be 8.11 nM for Hg 2+ and 2.09 nM for Ag + . 63 These values result almost 10 fold lower than similar reported calix [4] arene based systems [64][65][66][67] or other uorescent chemosensors. 68,69 Comparative data are displayed in Table S1.…”

“…Work from a few research groups have demonstrated the assembly of sugar-fluorophore conjugate, mostly macrocycles [133][134][135][136][137][138][139][140]; some have shown interesting photochemical properties in response to the presence of specific ions, such as Cu 2+ , Hg 2+ and Pb 2+ . BODIPY was also incorporated in some of these designs, and found to show binding to a selection of ions including Cu 2+ , leading to fluorescent quenching [138].…”

This review summarises the literature on the synthesis and applications of fluorescently labelled carbohydrates. Due to the sensitivity of fluorescent detection, this approach provides a useful tool to study processes involving glycans. A few general categories of labelling are presented, in situ labelling of carbohydrates with fluorophores, fluorescently labelled glycolipids, fluorogenic glycans, pre-formed fluorescent glycans for intracellular applications, glycan-decorated fluorescent polymers, fluorescent glyconanoparticles, and other functional fluorescent glycans.
