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.

Supramolecular polymer gels (SPGs) are precisely designed gels brought together by noncovalent interactions to form three-dimensional network structures of polymers. In general, SPGs are different from supramolecular gels as they...

In this work, three different monomers AB2, C2，and TP4 were synthesized. The AB2+C2 could self-assemble to form supramolecular hyperbranched polymer (SHP1) based on crown ether-based host-guest interaction. Upon adding TP4...

A sequence-controlled supramolecular copolymer was constructed by self-sorting assembly of metal coordination and two types of host–guest interactions.
