A platinum(II) metallacycle-cored supramolecular network based on a metal–salen complex was successfully constructed by two orthogonal noncovalent interactions (host–guest interactions and metal coordination interactions). The obtained metallo-supramolecular polymer could further form gels when the concentration of metallacycle 1 was 160.0 mM. This gel exhibited multiple stimuli-responsive gel–sol phase transitions under different stimuli, such as temperature, competitive guests, etc. Moreover, it exhibited good self-healing properties and could be used as a turn-off sensor for thiol-containing amino acids.

基于金属-Salen配合物的自修复金属环核超分子聚合物，由正交金属配位和主客体相互作用与氨基酸传感构成

通过两个正交的非共价相互作用（主客体相互作用和金属配位相互作用）成功构建了基于金属-salen 配合物的铂（II）金属环超分子网络。当金属环1的浓度为160.0 mM时，得到的金属超分子聚合物可以进一步形成凝胶。该凝胶在温度、竞争客体等不同刺激下表现出多种刺激响应的凝胶-溶胶相变。此外，它表现出良好的自愈性能，可用作含硫醇氨基酸的关闭传感器.
