Hydrogen-bonded liquid crystalline polymers have emerged as promising "smart" supramolecular functional materials with stimuli-responsive, self-healing, and recyclable properties. The hydrogen bonds can either be used as chemically responsive (i.e., pH-responsive) or as dynamic structural (i.e., temperature-responsive) moieties. Responsiveness can be manifested as changes in shape, color, or porosity and as selective binding. The liquid crystalline self-organization gives the materials their unique responsive nanostructures. Typically, the materials used for actuators or optical materials are constructed using linear calamitic (rod-shaped) hydrogen-bonded complexes, while nanoporous materials are constructed from either calamitic or discotic (disk-shaped) complexes. The dynamic structural character of the hydrogen bond moieties can be used to construct self-healing and recyclable supramolecular materials. In this review, recent findings are summarized, and potential future applications are discussed.
氢键液晶聚合物作为有前途的“智能”超分子功能材料，具有刺激响应、自修复和可回收的特性。氢键可以作为化学响应（例如，pH 响应）或动态结构（例如，温度响应）部分。响应可以表现为形状、颜色或孔隙率的变化以及选择性结合。液晶自组织赋予材料独特的响应性纳米结构。通常，用于致动器或光学材料的材料是使用线性棒状（棒状）氢键复合物构建的，而纳米多孔材料是由棒状或盘状（盘状）复合物构建的。氢键部分的动态结构特性可用于构建自修复和可回收的超分子材料。本文总结了最近的研究发现，并讨论了潜在的未来应用。
