A supramolecular polymer was constructed from a light-driven overcrowded alkene switch modified with two alkylated gallic acid amide pendants (MSP-1). Upon UV irradiation, stable MSP-1 isomerized into unstable MSP-2, which induced the effective collapse of well-defined cross-linked supramolecular polymers, and the reassembly can be realized by aging at low temperature.
一种超分子聚合物是由一个受光驱动的过度拥挤的烯烃开关构建的，该开关用两个烷基化的没食子酸酰胺侧链修饰（MSP-1）。在 UV 照射下，稳定的 MSP-1 异构化为不稳定的 MSP-2，这导致了定义明确的交联超分子聚合物的有效坍塌，并且可以通过在低温下老化来实现重组。
