“…[31][32][33][34][35][36] For cations, the sensing mechanism is normally governed by coordination induced charge transfer, while the hydrogen bonding induced charge transfer mechanism is common for anions. Notably, the structural framework of probes which are sensitive and selective for anions are usually characterized by amine, 37,38 hydroxyl, 39 sulfonyl, 40 urea 41,42 and hydrazone [43][44][45] groups, while cation probes normally bear so donor atoms such as oxygen, nitrogen and sulfur. However, there are other interaction mechanisms, governed by weak Van der Waals forces, which can induce the sensing of cations and anions.…”

“…So, considerable effort has been devoted to the development of AcO − chemosensors in recent years . But some AcO − chemosensors are often disturbed by the basic anions, including F − , H 2 PO 4 − and PO 4 3− [37][38][39][40][41][42][43]. Moreover, it is well-known to the fluorescent chemosensors that the ability for the long-wavelength emissions can avoid the possible influence of background fluorescence effectively, which can also improve their selectively and sensitivity [44][45][46].…”

A novelty chemosensor MM to detect AcO − was designed, synthesized and characterized. When MM interacted with AcO − , it was found that the new fluorescent emission peak at 616 nm arose. Meanwhile, the color change of the solution was directly observed by the naked-eye. Interesting, other anions could not cause any interference, specially F − , H 2 PO 4 − and PO 4 3−. The possible interaction mode between them was confirmed based on the Job's plot, 1 H NMR titration, ESI-MS, SEM analysis and DFT calculation. And LOD (limit of detection) of MM toward AcO − was 4.6 nM. Moreover, MM could be utilized as test strips to identify AcO − qualitatively. It's more important that MM could realize to detect AcO − in tap water quantitatively, rapidly and on-site by used of smartphone APP. Furthermore, MM was successfully applied to detect AcO − in living Caenorhabditis elegans. And it also demonstrated its potential bioimaging in living system.

A Schiff's base derivative was synthesized using a condensation reaction between 8formyl-7-hydroxy-4-methylcoumarin and furan-2-carbohydrazide that produced marked aggregation-induced emission and had excellent ability to specifically recognize aluminium ions (Al 3+ ). This compound displayed faint fluorescence in the benign solvent dimethyl formamide, and exhibited obvious green fluorescence following addition of specific amounts of water. Moreover, it exhibited strong blue fluorescence after combination with Al 3+ even in the presence of other interfering ions.These experimental results demonstrated that this derivative could be used as a fluorescence probe for Al 3+ . The advantages, including significant fluorescence change, high selectivity and sensitivity, and fast response, meant that this probe could be used both to detect Al 3+ in water samples and for fluorescence imaging in living cells.
