分子折叠体是一类由非共价键稳定的、采用有序构象的寡聚物或聚合物.我们设计并合成了三类非天然的折叠体,包括:(1)由疏溶剂作用驱动的并入萘环板块的寡聚乙二醇折叠体,(2)由分子内氢键驱动的寡聚酰肼折叠体,(3)由分子内氢键驱动的并入锌卟啉板块的寡聚苯酰胺折叠体.定性和定量的研究揭示,在有机溶剂中这些折叠体可以作为非天然受体分子高效络合或识别结构匹配的有机分子和离子,并且氢键驱动的折叠体可以通过络合作用实现超分子体系的手性诱导或手性放大.
Molecular Folding is a class of non-covalently bonded, oligomerized or ordered conformational oligomers.We have designed and synthesized three types of non-natural folds including: (1) driven by the action of a solvating agent (2) oligomeric hydrazide hydrides driven by intramolecular hydrogen bonds, (3) oligomeric hydrazide chains driven by intramolecular hydrogen bonding to incorporate zinc porphyrin plates Benzamide Follicles Qualitative and quantitative studies revealed that these folds can efficiently complex or recognize structurally matched organic molecules and ions as non-natural acceptor molecules in organic solvents and that the hydrogen-bond driven pleats can be complexed The role of supramolecular system to achieve chiral induction or chiral amplification.
