摘要超分子聚合物（Supramolecular polymer）是指小分子单体利用分子间的可逆非共价 键作用自组装形成的类似高分子般的体系。与传统的共价键高分子聚合物相比较，超分子聚 合物体系中非共价键的存在使得超分子聚合物具有结构动态可调、对外界环境具有刺激-响 应性、自修复性能及优异的加工性能等诸多优异性质。因此，近年来超分子聚合物越来越受 到科研工作者们的关注，已经发展成为了一门独立的新兴学科。为此，本论文主要目的是通 过分子设计引入具有 AIE 效应的四苯基乙烯荧光团，以三联吡啶与金属离子的金属配位作 用和冠醚基团与二级铵盐之间的主客体相互作用为驱动力，来研究功能化的超分子聚合物材 料。我们设计合成了由中间为双苯并 24-冠-8 的冠醚连接两个四苯基乙烯荧光生色团，两 端为两个三联吡啶分子构成的一个主体分子。通过主体分子两端的三联吡啶基团与金属锌离 子发生 1:1 金属配位形成线型超分子聚合物，之后再以中间的冠醚基团为接入位点，与二级 铵盐之间发生主客体相互作用，分级自组装形成了一种交联网状超分子聚合物。当提高浓度 至 30 mmol 时，可形成超分子有机凝胶。该有机凝胶对环境中的温度、酸碱性等都具有很 好的刺激响应性，并且在被大面积破坏的情况下可自行修复。这种材料未来可以应用于人工 智能和化学传感器等领域。88609

Abstract Supramolecular polymer refers to the use of intermolecular reversible non-covalent bond to self-assemble the polymer-like system。 Compared with conventional covalent polymer macromolecules，the presence of non-covalent bonds From优T尔K论M文L网wWw.YouERw.com 加QQ75201^8766

in the supramolecular polymer system makes the supramolecular polymer have some excellent properties, such as dynamic adjustable structure, stimulus-response, self-repairing performance and excellent processing performance in the external environment。 Therefore, in recent years, supramolecular polymers are increasingly concerned by researchers and developed into a separate emerging disciplines。 Research and development of multi-functional supramolecular  polymer  materials have become a hot topic in recent years。 Based on the non-covalent bonds, the supramolecular polymer can not only be widely used in the biological field, such as biological drug loading, biomimetic device, tissue engineering and so on, but also for intelligent materials because of its good stimulating responsiveness and self-repairing。 In this paper, the main purpose of this paper is to investigate the functionalized supramolecular polymer materials containing the tetrateylethylene fluorophore with AIE effect, which are formed by the coordination of terpyridine ligand with metal ions and the interaction between the crown ether and the secondary ammonium salt introduce。 A host molecule with a di-benzo-24-crown-8 liking  two tetraphenylethylene fluorescence chromophore in the middle and two terpyridine molecules at both ends was synthesized The supramolecular polymer was formed by the 1:1 coordination of zinc ions with tripyridine groups, followed  by  the intermediate crown ether group as the access site and the secondary ammonium salt。 The interaction between the host and guest leads to the formation of a cross-linked network of supramolecular polymer by self-assembly。 When the monomers’ concentration increased to 30mM, a supramolecular polymer gel can be formed。 This supramolecular polymer gel has a good stimulating response to the temperature, acidity in the environment and a good self-healing property in the case of large area destruction。 This material can be used in the field of artificial intelligence and chemical sensors in the future。
