Supramolecular polymer materials are polymeric structures that are physically crosslinked by non-covalent interactions such as ionic interactions, host-guest complexation and hydrogen bonding. The resulting materials generally display stimuli-responsive behavior and/or healable properties, which makes them excellent candidates for the design of dynamic materials. Inspired by its omnipresence in natural systems, hydrogen bonding has proven to be useful for the development of synthetic materials with dynamic properties. Inspired by the base-pairing in the DNA double helix, Meijer et al. developed the self-complementary quadruple hydrogen bonding unit ureidopyimidinone (UPy), which has a strong dimerization constant (K_dim > 10⁷ M ⁻¹ ). The incorporation of UPy motifs in polymeric precursors led to a plethora of hydrogen bonded materials with applications ranging from artificial arteries to reversible adhesives. This review will focus on design strategies to synthesize these UPy-containing polymer materials, which can be split into three main categories based on the location of the UPy arrays: UPy in the main-chain, UPy in the side-chains or UPy at the chain-ends. In addition to the synthetic routes, the material properties of the resulting UPy-containing supramolecular polymer materials will be discussed.

超分子高分子材料是通过离子相互作用、主客体络合和氢键等非共价相互作用物理交联的高分子结构。由此产生的材料通常表现出刺激响应行为和/或可修复特性，这使它们成为动态材料设计的绝佳候选者。受其在自然系统中无处不在的启发，氢键已被证明可用于开发具有动态特性的合成材料。受 DNA 双螺旋中碱基配对的启发，Meijer 等人。开发了自互补四重氢键单元脲基嘧啶酮 (UPy)，它具有很强的二聚化常数 (K _dim > 10 ⁷ M  ⁻¹ ). 在聚合物前体中加入 UPy 基序导致产生了大量的氢键合材料，其应用范围从人造动脉到可逆粘合剂。本综述将重点介绍合成这些含 UPy 聚合物材料的设计策略，根据 UPy 阵列的位置，这些材料可分为三大类：主链中的 UPy、侧链中的 UPy 或链上的 UPy。链端。除了合成路线外，还将讨论所得含 UPy 的超分子聚合物材料的材料特性。
