【 摘 要 】

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.
