Supramolecular silicone materials are promising candidates toward sustainable and recyclable applications. Herein, quadruple hydrogen bond motifs are introduced into the main chain of polysiloxane for the first time, providing a new type of supramolecular silicone elastomers. This structural design enables the well-defined spacing length between ureidopyrimidinone (UPY) units, exercising better control over polymer network structure. The obtained materials exhibit elastomeric properties and robust reprocessability, and can be further developed into europium (Eu)-coordinated elastomers with interesting water-responsive luminescence. It is highly anticipated that this work will broaden the scope and application of silicone-based sustainable materials.

通过自互补四重氢键合的聚（硅氧烷-氨基甲酸酯）可再加工超分子弹性体

超分子有机硅材料是可持续和可回收应用的有希望的候选者。在此，首次将四重氢键基序引入聚硅氧烷主链，提供了一种新型的超分子有机硅弹性体。这种结构设计使脲基嘧啶酮 (UPY) 单元之间的间距长度明确，从而更好地控制聚合物网络结构。获得的材料表现出弹性性能和强大的可再加工性，并且可以进一步开发成具有有趣的水响应发光的铕（Eu）配位弹性体。人们高度期待这项工作将扩大有机硅可持续材料的范围和应用。
