“…Schiff bases can be used to modify NPs by surface modification methods such as grafting and encapsulation, and a variety of ion sensors have been fabricated. ,− Actually, organic NPs of Schiff base complexes can also be directly prepared. − For instance, Singh et al synthesized a Schiff base based tripod receptor and obtained a zinc complex on this basis, which can be used for the detection of F – and HSO 4 – . The fluorescence peak at 422 nm was enhanced by the addition of F – because the cavity interaction of F – in the complex which resulted in the separation of two aromatic nitro rings and inhibited the photoinduced electron transfer (PET) effect.…”

Ion detection is crucial for environmental quality, human health, and industry development. Schiff bases and their complexes are widely applied as the probes for ion detection in chemistry, environment, and biology fields. There are many kinds of interesting Schiff bases and their coordination complexes that have been designed and synthesized based on the facile synthesis. Recently, Schiff base chemistry has intercrossed with nanomaterials toward wide applications. Nanomaterials are characterized by their sizes in the range of several nanometers to several hundreds of nanometers and then with large specific surface area. They have unusual properties such as mechanical property, optical property, and catalytic property, which are usually not active for their bulk materials. The development of new nanomaterials has dramatically increased in the past two decades, especially the hybridization of inorganic nanomaterials with organic functional species. Schiff base is a very famous class of organic molecules with diversity structures and properties. The remarkable point is that they are synthesized facilely. In this review, the principles and methods of Schiff base preparation have been scanned briefly. Then nanomaterials functionalized by Schiff base to achieve efficient, rapid, and sensitive recognition of ions were elaborated. The types of nanomaterials are included the metal–organic frameworks (MOFs) and covalent organic frameworks (COFs) constructed by Schiff base ligands with nanosized pores and surface modification of nanoparticles (NPs) with Schiff bases, which can not only retain the advantages of the original nanomaterials but also improve the ability of ion-specific recognition. The development of colorimetric, fluorescence, and electrochemical sensors based on Schiff base nanomaterials for ion detection in recent years was carefully summarized as well. It should be mentioned that the types of ions in this review are mainly metal ions. Finally, the challenges in the future in this field have been proposed.

environment for luminophores, but also restricts the movement of guests, inhibits the nonradiative transition of the excited state of luminophores, reduces the collision of solvent molecules, giving a confined microenvironment for phosphorescence emission. [14][15][16] Tian et al. [17] reported that CB[8] could bind with triazine bridged bromophenyl pyridine derivative to form a stable 2:2 hostguest complex, then could be excited by visible light to give tunable phosphorescence emission in aqueous solution. We reported a red phosphorescence emission "supramolecular pins" with ultrahigh quantum yield up to 99.38% based on CB[8] and alkyl chain bridged phenyl pyridine salt. [18] Thus, the confinement of CBs can effectively induce RTP emission of organic luminophores. In addition, nanosized supramolecular assemblies not only have assemble confined effect is benefit to improving the luminescent properties of chromophores, but also could further load dyes as energy acceptors to form efficient energy transfer system. Therefore, taking advantage of the strategy of confinement of macrocyclic compounds and assemble could effectively promote the development of PLH systems.Artificial light-harvesting system with the characteristics of large donor-acceptor ratio and high energy transfer efficiency, which is convenient to realize large Stokes shift luminescence emission, showing fascinating application prospects in the fields of cell imaging, [19][20][21] sensor detection, [22] catalysis, [23][24][25] and luminescent materials. [26][27][28] George et al. reported that luminescent supramolecular hybrid could be facilely fabricated by the cationic dibromophthalimide derivative and inorganic clay via electrostatic interaction, exhibiting efficient phosphorescence emission with high quantum yield as 41.8%, which also could be doped with energy acceptor to form artificial lightharvesting system. [29] We reported that dibromophthalimide derivative could coassemble with CB[7] and amphipathic sulfonatocalix[4]arene to form multivalent phosphorescence assembly, then loading dyes as energy acceptors to construct near-infrared emission PLH system with cascaded energy transfer for cell imaging. [20] However, the application of pure organic PLH system with long lifetime luminescence in photocatalysis reaction has not been reported as best we know. Herein, a doublenetwork PLH system was successfully fabricated by in situ copolymerization of bicationic vinyl bromophenyl pyridine derivative (G), CB[8], acrylamide, and hyaluronic acid modified

“…Photosynthesis (the light-harvesting system in nature) is very important to life on earth. 9 In this process, numerous tightly packed antenna pigments (approximately 200) acting as donors around the reaction centre are employed to absorb, accumulate and transfer solar energy to the acceptor at the reaction centre. [10][11][12][13][14] Therefore, donors are critical in a light-harvesting system, and good donors are the foundation of efficient ALHSs.…”
