Perspectives on the modification of electrodes by polymers of intrinsic microporosity (PIMs) for electroanalysis

Frank Marken, Dorottya Szalay, Neil B. McKeown, Mariolino Carta et autres

Extreme molecular rigidity in the polymer backbone introduces new properties in polymer films or coatings in contact with solution, electrodes, and embedded catalysts. Polymers of intrinsic microporosity (PIMs) with highly rigid molecular structures have initially emerged as gas separation and storage materials. …
