课题组关于自修复聚集诱导发光超分子聚合物及凝胶的研究以封面论文发表在Macromolecules 2020, 53, 4255-4263上。

In this work, two TPE-bridged monomers M4 and N4, and a heteroditopic monomer AE were designed and synthesized. They could self-assemble by self-sorting mode to form supramolecular cross-linked alternating polymer. The process of supramolecular polymerization induced fluorescence emission enhancement on the basis of an AIE mechanism. Furthermore, the “off-on” switchable fluorescence emission could be achieved by adding-removing potassium ion from the solution of supramolecular polymer or heating?cooling method. At relatively high concentration, the supramolecular cross-linked polymer transformed into supramolecular gel and the obtained gel showed excellent self-healing capability and thermal reversibility.
