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 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-水杨醛络合物的以铂（II）金属环为核心的超分子网络通过两种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。当金属环浓度为160.0 mM时，所得金属超分子聚合物可进一步形成凝胶。该凝胶在不同刺激（如温度、竞争性客体等）下表现出多种刺激响应的凝胶-溶胶相变。此外，它还表现出良好的自愈性能，可作为含硫醇氨基酸的关闭型传感器。
