Abstract

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.

基于脲嘧啶四重氢键单元的超分子高分子材料

超分子高分子材料是通过离子相互作用、主客体络合作用和氢键等非共价相互作用进行物理交联的高分子结构。所得到的材料通常表现出刺激响应行为和/或可治愈性，这使它们成为动态材料设计的优秀候选人。受其在自然系统中无处不在的启发，氢键已被证明对开发具有动态特性的合成材料是有用的。受到DNA双螺旋碱基配对的启发，Meijer等人开发了自互补的四重氢键单元脲嘧啶(UPy)，它具有很强的二聚化常数(Kdim >107 m−1)。UPy基序在聚合物前体中的结合导致了大量的氢键材料，其应用范围从人造动脉到可逆粘合剂。本文将重点介绍合成这些含UPy聚合物材料的设计策略，根据UPy阵列的位置可将其分为三大类:主链上的UPy，侧链上的UPy或链端上的UPy。除了合成路线外，还将讨论所得含upy的超分子高分子材料的材料性质。
