Application of new strategies for supramolecular self-assembly can significantly impact the properties and/or functions of supramolecular polymers. To realize a facial strategy for the development of solvent-free supramolecular polymers in bulk, "deep eutectic solvents" were employed. Cyclodextrins and natural acids were used to prepare deep eutectic supramolecular polymers (DESPs). Deep eutectic solvents have special characteristics that endow DESPs with unique macroscopic properties and excellent processability. DESPs exhibit supramolecular adhesion and temperature-dependent behavior originating from the combined effects of deep eutectic solvents and supramolecular polymerization. Because DESPs are solvent-free and display interesting macroscopic properties, they have potential as new adaptive materials.
超分子自组装新策略的应用可显著影响超分子聚合物的性质和/或功能。为了实现一种简便的策略来开发本体无溶剂超分子聚合物，采用了“深共熔溶剂”。环糊精和天然酸被用于制备深共熔超分子聚合物（DESPs）。深共熔溶剂具有特殊性质，赋予DESPs独特的宏观性质和优异的加工性能。DESPs表现出超分子粘附性和温度依赖性行为，这源于深共熔溶剂和超分子聚合的综合作用。由于DESPs无溶剂且展现出有趣的宏观性质，它们具有作为新型自适应材料的潜力。
