Abstract

Semirigid poly(N-aryleneindole ether sulfone) (PESIN) as a fluorescence emission on–off switch has been successfully achieved via the cation–π interactions. The adjustment of the protonation/deprotonation status of pyridine that regulates the formation of cation–π interactions is definitely the determinant.
