A linear AIE supramolecular polymer was constructed by a salicylaldehyde azine-containing pillar[5]arene dimer P5D and a homoditopic guest G. The linear supramolecular polymer displayed strong fluorescence at high concentration. It displayed crosslinked structure and fluorescence quenching property after the addition of Cu II and recovered after the addition of cyanide.

Adhesion between hard materials without any glue is challenging and difficult. Supramolecular chemistry provides an innovative and feasible solution to realize it by non-covalent interactions. Here, we realized adhesion between...
