[Abstract]:The main contents of this thesis are the construction of one-dimensional, two-dimensional (2D) supramolecular polymers and covalent organic frameworks (COFs) based on CB [8] inclusion enhanced donor-receptor interaction, as well as iodine adsorption. The main content includes the following three parts. The first part is a supramolecular polymer brush based on CB [8] inclusion to enhance donor-receptor interaction. In this work, we have designed and synthesized a rigid molecule T1 with an electrically deficient violet fragment and a electrically rich naphthol motif T2 with two flexible chains of tetraethylene glycol. By self-assembly in aqueous solution, a novel supramolecular polymer brush was constructed for the first time. The formation of linear supramolecular polymer brushes was proved by nuclear magnetic titration, UV, dynamic light scattering (DLS) and two-dimensional diffusion ordered nuclear magnetic resonance spectroscopy (DOSY). In the second part, the two-dimension self-assembly in water is improved by amphiphilic modification. A highly ordered two-sided 2D supramolecular organic framework (SOFs) is constructed. In this part of the work, we designed a hydrophobic chain modified pyridine salt with trianiline as the core skeleton. By interacting with the host and guest of CB [8], we formed a highly ordered two-sided 2D supramolecular organic framework. Transmission electron microscopy (TEM), atomic force microscope (AFM) and synchrotron radiation small angle scattering (SAXS) were used. The morphologies of the two different supramolecular polymers were observed directly. At the same time, it is proved that the pre-assembly formed by amphiphilicity has an important effect on the preparation of highly ordered internal assembly materials. The third part deals with the adsorption of hollow spheres formed by heteroporous covalent organic frameworks and their ultrahigh volatile iodine elements. Covalent organic frameworks are widely used in photovoltaic materials, catalysis, gas adsorption, transfer of guest molecules and so on. But its topology structure is limited, so it is urgent to develop new application direction. In this part of the work, we designed and synthesized a new topological structure COFwith hexagonal structure and parallelogram structure by using p-phenylenediamine in solvothermal condition. This kind of COF can form micro-nano hollow spheres and has a high adsorption capacity for volatile iodine. The work in this part not only expands the topological diversity of covalent organic frame, but also expands the diversity of application of covalent organic frame.
