Abstract
A supramolecular brush polymer Poly(P5-OXD) was constructed through the self-assembly of an A1/A2 disubstituted pillar[5]arene P5-OXD with a 1,3,4-oxadiazole unit and a cyanobutoxy group, exhibiting external stimuli responsiveness towards Cu2+ ions with an ON/OFF fluorescence signal output.
