Well-defined polymers containing a single mid-chain viologen group: synthesis, environment-sensitive fluorescence, and redox activity

“…PhNHNH 2 is relatively stable in air and its oxidation, which yields nitrogen and a complex mixture of other products, generally requires harsh conditions. 64 The efficient oxidation of toxic compounds (such as phenylhydrazine) to less toxic ones is appealing due to its potential in the decontamination of water or soil. When the compound was added to a solution of the viologen-containing polymers, an intense blue color developed very rapidly.…”
