In this work, three different monomers AB2, C2, and TP4 were synthesized. AB2 + C2 could self-assemble to form a supramolecular hyperbranched polymer (SHP1) based on crown ether-based host–guest interaction. Upon adding TP4 into the solution of SHP1, SHP1 transformed into a higher molecular weight supramolecular cross-linked polymer (SCP1), accompanied by a dramatic fluorescence emission enhancement due to the aggregation of the tetraphenyl ethylene core induced by supramolecular polymerization. A supramolecular gel with blue fluorescence emission was generated when the concentration of SCP1 exceeded 64 mM. Adding/removing K⁺ or heating/cooling the gel could realize reversible gel–sol transition, accompanied by the decrease or enhancement of the fluorescence emission intensity. Moreover, the supramolecular gel with AIE properties showed excellent self-repairing capability.

超分子聚合物通过分层自组装的体系结构转变：从超分子聚合物到荧光材料

在这项工作中，合成了三种不同的单体AB2，C2和TP4。AB2 + C2可以基于冠醚基的主客体相互作用而自组装形成超分子超支化聚合物（SHP1）。在SHP1溶液中加入TP4后，SHP1转变为更高分子量的超分子交联聚合物（SCP1），由于超分子聚合引起的四苯基乙烯核的聚集，荧光增强了。当SCP1的浓度超过64 mM时，产生具有蓝色荧光发射的超分子凝胶。添加/删除K ⁺或加热/冷却凝胶可实现可逆的凝胶-溶胶转变，同时降低或增强荧光发射强度。此外，具有AIE特性的超分子凝胶表现出出色的自我修复能力。
