Synthesis And Properties Of Quinoline-functionalized Multipod-amide Supramolecular Materials

The quinoline structure is a fused ring system consisting of pyridine and benzene rings,which has shown great potential in supramolecular chemistry due to its diversity of functional groups and ability to form various intermolecular interactions.Supramolecular chemistry is an interdisciplinary field of research that focuses on noncovalent interactions between molecules and how they influence the formation of larger,more complex structures.In this text,the latest advances in supramolecular chemistry of quinoline derivatives are reviewed.The various intermolecular interactions that these molecules can form,including hydrogen bonding,π···πstacking,and metal coordination,are discussed,as how these interactions can be used to create supramolecular structures,such as molecular cages,gels,and porous crystals.Potential applications of quinoline derivatives in supramolecular chemistry,including fluorescence sensing,adsorption and separation of toxic gases,catalysis,and cell imaging,are also highlighted.Overall,the supramolecular chemistry of quinoline derivatives offers a promising avenue for designing novel functional materials with unique properties and potential applications in a wide range of fields.Firstly,the design and construction of supramolecular materials based on quinoline multipodalamide and their applications in various fields in recent years are studied and summarized.Then,based on the design and construction of quinoline-functionalized supramolecular materials by our research group and its research on the detection and adsorption of toxic gases,fluorescent sensors,multiple stimulus responses,quantum dots,etc.,further exploration of multipodalamide quinoline functionalized supramolecular material detection and adsorption of toxic gases,explosives,and anions and their multiple stimulus-response performances.The first part:By consulting a large number of literature and reviews on multipodal quinoline and quinolinamide supramolecular materials,the preparation of different quinoline-functionalized multipodal-amide supramolecular materials and their research progress in various fields were summarized.Through the design and construction of a series of supramolecular materials,the detection,and adsorption of toxic ions and molecules,cell imaging,catalysis,and fluorescence sensing are realized.Meanwhile,put forward your research topics and design ideas in combination with the relevant research methods of the course group.The second part:Supramolecular smart material(DQ8)was successfully prepared by introducing quinoline structure into both ends of naphthalimide reasonably.The introduction of quinoline groups can produce a“synergistic effect”,providingπ...πself-assembly binding sites,while also producing multiple stimulus responses to guest molecules.The third part:A tripod fluorescent supramolecular hydrogel(TQ8)was designed and synthesized by introducing quinolinamide group,which can provide multiple hydrogen bonding sites,thereby improving the assembly capacity of supramolecular gel and producing a significant stimulus response to picric acid.The fourth part:A novel diquinoline functionalized naphthalene diformimide supramolecular gel(DQ8-g)was designed and synthesized.It was confirmed by NMR titration and theoretical calculation that the DQ8-g gel’s response to CN~-fluorescence was induced by deprotonation,and it was also based on the anion···πsynergistic interaction between naphthalimide and quinoline.
