【摘要】：超分子聚合物材料是高分子科学、超分子化学和材料科学3个学科相结合的产物.通过精妙的设计,我们不仅可以赋予它传统高分子材料所拥有的光学、电学以及力学等性能,同时还可以使其具有超分子材料的动态可逆性和刺激响应性.已用于构筑超分子聚合物材料的主客体识别体系有很多,从识别体系中的主体来说,包括基于冠醚、环糊精、杯芳烃、葫芦脲、柱芳烃等大环的主客体体系.其中,冠醚作为第一代大环主体,它的模板合成直接开辟了超分子化学这一领域,而柱芳烃是最近发展起来的一类新的大环主体,它具有刚性的骨架,并且制备简单,容易功能化,同样也受到超分子化学家们的广泛关注.本文着重综述了我们课题组基于冠醚和柱芳烃主客体识别所构筑的超分子聚合物材料.在这些材料的制备中,我们利用了主客体识别的刺激响应性、可逆性和选择性,来实现对这类材料的组装结构以及功能的精确调控.
[Abstract]:Supramolecular polymer materials are the combination of polymer science, supramolecular chemistry and material science. Through the subtle design, we can not only endow the traditional polymer with the optical, electrical and mechanical properties, but also have the dynamic reversibility and stimulus response of the supramolecular materials. There are many host and guest recognition systems which have been used to construct supramolecular polymer materials, including the host and guest systems based on crown ether, cyclodextrin, calixarene, cucurbituron, column aromatics and so on. Among them, crown ether as the first generation macrocyclic host, its template synthesis directly opens up the field of supramolecular chemistry, and column aromatics is a new kind of macrocyclic host recently developed, it has rigid skeleton and simple preparation. Easy to functionalize, but also by the broad attention of supramolecular chemists. The supramolecular polymer materials based on crown ether and column aromatics are reviewed in this paper. In the preparation of these materials, we make use of the stimuli responsiveness, reversibility and selectivity of the host and guest recognition to achieve the precise regulation of the assembly structure and function of these materials.
