摘要
构建手性光学开关是手性科学与技术领域最具有挑战性的前沿课题之一。经典的手性光学开关是以手性或非手性的分子为基材,近年来,以手性或非手性的无机纳米颗粒为基材构筑手性无机纳米超结构的研究极大地拓宽了手性光学开关的研究范畴。DNA折纸纳米模板由于结构可设计性和空间寻址能力,在精确引导无机纳米颗粒自组装形成预设结构和性能方面具有显著的优势。然而,与之相比,糖类超分子模板来源更加丰富,适用于大规模制备手性无机纳米超结构材料;糖类超分子模板富含糖基,可为后续组装无机纳米颗粒提供丰富的结合位点;糖类超分子模板可通过常规的化学方法引入刺激响应基团,将极大拓宽手性无机纳米超结构在手性光学开关中的应用。本研究利用糖类分子为手性源,开发基于糖类超分子模板的可控可逆的手性无机纳米超结构,发展其在手性光学开关中的应用,为构筑可控可逆的手性无机纳米超结构建立一种廉价、普适、快捷有效的超分子模板技术。
Construction of chiroptical switches is one of the most challenging frontier topics in the field of chiral science and technology. Classic chiroptical switches were fabricated using chiral or achiral molecules as building blocks, in recent years, research on construction of chiral inorganic nanoparticle superstructures using chiral or achiral inorganic nanoparticles as building blocks has greatly broadened the research scope of the chiroptical switches. This research mainly focused on developing the controllable reversible chiral inorganic nanoparticle superstructures based on the carbohydrate supramolecular templates using the carbohydrate molecules as chiral sources, and exploring their applications in the chiroptical switches.
