Description

TECHNICAL FIELD

[0001] The present application relates to a preparation method of chiral diacetylene molecules, supermolecular assembly of which forms fibers, and topological polymerization method and application thereof. BACKGROUND

[0002] Supermolecular assembly, combining the dynamic characteristics of supramolecular chemistry and the response characteristics to external stimuli, opens up a new way for creating new supramolecular materials. Stimulus-responsive supramolecular overcomes the shortcomings of traditional covalent chemistry and can be easily formed in different ways. In addition, supramolecular assembly with stimulus-responsive characteristics can control the interaction balance between different structural units through external stimuli to realize in-situ adjustment of its supramolecular structure, thereby changing its assembly mode. Various stimuli sources have been used to prepare intelligent supramoleculars, among which light is one of the most prominent stimulation methods because it is a clean and easy-to-obtain stimulus source. Although supramolecular materials have various structural and functional advantages, due to their dynamic characteristics, their structural stability is limited, and there are certain defects in practical applications. Therefore, the conversion of supramolecular polymers with multiple functions connected by non-covalent bonds into stable covalent polymers connected by covalent bonds has attracted special attention in recent years. Among them, one of the remarkable features of diacetylene (DA) supramoleculars is that they can undergo photo-induced polymerization to generate polydiacetylene (PDA) in-situ, without introducing impurities or generating new impurities, making DA-containing supramoleculars particularly meaningful for the manufacture of covalent polymers with hierarchical structure.

[0003] In addition, alkoxyl ether dendronogen is a kind of dendritic topological structure with certain hydrophilic properties. When it is combined with diacetylene and polypeptide elements are introduced at the same time, a kind of dendritic diacetylene polypeptide with amphiphilic and chiral characteristics can be obtained, so that chiral supramolecular assembly in aqueous solution can be carried out. Compared with supramolecular assembly in organic solution, supramolecular assembly in aqueous solution has more potential value in the biological field, so the study of supramolecular assembly of chiral dendritic diacetylene in water and its topological polymerization is of great significance for the construction of new supramolecular materials.
