摘要:

超分子凝胶作为一种重要的软物质材料,在构建多重刺激响应性、光电功能,以及生物相容材料等功能软物质方面表现出了独特的优越性。超分子凝胶在形成过程中往往得到比较均一的纳米结构,且具有结构多样性;而另一方面,超分子凝胶的构筑单元大部分是手性分子,超分子凝胶也是实现手性在超分子层次/纳米层次表达的重要途径,尤其是手性传递、手性放大、不对称催化方面,同时超分子凝胶也是构筑手性纳米结构的重要手段。本文主要对超分子凝胶形成中的纳米结构以及形貌的多样性和超分子手性进行介绍,并展望该领域未来的发展方向。

Abstract:

supramolecular gels, an important type of soft matter, have showed unique advantages in the construction of functional soft materials, such as multiple stimuli responsive, photoelectrical, and biological compatibility materials. Through supramolecular gelation, diverse, uniform nanostructures can be obtained in a large quantity. On the other hand, most gelators are chiral molecules, so supramolecular gel is a medium to realize the expression of the chirality in supramolecular and nano level, especially to realize effectively chirality transfer, amplification, and asymmetric catalysis, and to fabricate various chiral architectures. In this paper, we describe the structural diversity and chirality in supramolecular gels, and discuss the future prospects for supramolecular gels.

Key words: supramolecular gel, Self-assembly, Nanotube, Helical and twisted ribbons
