Control over the adhesive properties are of great importance for both biological and chemical systems. Herein, we use amino‑yne click reaction to prepare metallacycle-crosslinked supramolecular polymer networks, which are further employed as reversible adhesive materials. The introduction of metallacyclic structures not only gives the formed polymer networks good emission and self-healing properties, but also affords improved adhesion strength and increased glass transition temperature, making them serve as reversible and emissive supramolecular adhesives. This study provides an efficient strategy for the preparation of functional supramolecular polymer networks towards adhesive applications.

对于生物和化学系统而言，控制粘合性能都非常重要。在这里，我们使用氨基炔点击反应来制备金属环交联的超分子聚合物网络，并将其进一步用作可逆粘合剂材料。金属环结构的引入不仅使所形成的聚合物网络具有良好的发射和自修复性能，而且还提供了改进的粘合强度和增加的玻璃化转变温度，使其成为可逆和发光的超分子粘合剂。这项研究为制备功能性超分子聚合物网络以实现胶粘剂应用提供了有效的策略。
