The controlled synthesis of monodisperse, redox-active metallopolymers and their redox properties functions, including robust electrode derivatization sensing, remains a challenge. Here series polynorbornene homopolymers block copolymers containing side-chain amidoferrocenyl groups tetraethylene glycol linkers were prepared via living ring-opening metathesis polymerization initiated by Grubbs' third-generation catalyst (1). Their molecular weights determined using MALDI-TOF mass spectra, size exclusion chromatography (SEC), end-group analysis, the empirical Bard–Anson electrochemical equation. All polymerizations followed manner, number units varied from 5 to 332. These successfully used prepare modified Pt electrodes that showed excellent stability. show qualitative sensing ATP2– anions, in particular those with copolymers. quantitative recognition titration [n-Bu4N]2[ATP] was carried out CH2Cl2 solution homopolymers, showing two interacted each molecule. This stoichiometry led us propose H-bonding modes supramolecular polymeric network.
