Abstract

We report a new block copolymer bearing p-fluoronitrobenzoate (FNB) pendants that is capable of responding to the H₂S_n biosignal in an extraordinarily selective and sensitive manner. This kind of polymer can further self-assemble into 1D rod-like nanoparticles in aqueous media and manifest H₂S_n specific-triggered particulate disassembly through H₂S_n-induced cleavage of side functionalities.
