One-dimensional,Two-dimensional Supramolecular Polymers And Heteropore Covalent Organic Framework Of Its Application

The main contents of this paper are the construction of one-dimensional,two-dimensional (2D) supramolecular polymers on the basis of cucurbit[8]uril-encapsulation-enhanced donor-acceptor interaction and heterogeneous covalent organic frameworks(Covalent Organic Frameworks, COFs) and iodine adsorption. The main contents include the following three parts.The first part of the work is a supramolecular bottlebrush polymer assembled on the basis of cucurbit[8]uril-encapsulation-enhanced donor-acceptor interaction. In this part,we designed and synthesized a rigid molecule of hypoxic brux segments and an enriched naphthol elementary molecule with two triethylene glycol flexible chains. A new type of supramolecular polymer brush was constructed for the first time by self -assembly in aqueous solution. The formation of linear supramolecular bottlebrush polymer was demonstrated by 1H NMR titration experiment, UV-vis experiment,dynamic light scattering (DLS), and 2D 1H NMR diffusion ordered spectroscopy(DOSY).The second part of the work is improving two-dimensional self-assembly in water through amphiphilic modification: toward a Janus 2D supramolecular organic framework (Supromolecular Organic Framework, SOFs) with high degree of internal order. In this part, we designed a pyridine salt component with triphenamine as the core skeleton modified by the amphiphilic chains, and formed a highly internal order Janus 2D supramolecular organic framework by the host-guest interaction. The morphological characteristics of the two different supramolecular polymers were observed by transmission electron microscopy (TEM), atomic force microscopy (AFM),solution-phase synchrotron small angle X-ray scattering (SAXS). It also demonstrates the important effect of preassembling formed by amphipathy on the preparation of internal highly ordered assembly materials.The third part of the work is ultrahigh volatile iodine uptake by hollow microspheres formed from a heteropore covalent organic framework. Covalent organic frameworks have a wide range of applications in optoelectronic materials,catalysis,gas adsorption,transfer of guest molecules and other fields. But its topology is limited and the urgent need to develop new applications. In this part, we designed and synthesized a hex-aldehyde, formed with p-phenylenediamine under solvent thermal conditions with hexagonal structure and parallelogram structure of the new topology of the COF. This COF can form micro-nano hollow microshperes and has an extremely high adsorption capacity for the volatile iodine. This part of the work not only extends the topology of covalent organic frameworks, but also expands the application of covalent organic framework.
