Redox-active catechols are bioinspired precursors for ortho-quinones that characterized by higher discharge potentials than para-quinones, the latter being extensively used as organic cathode materials lithium ion batteries (LIBs). Here, this study demonstrates rational molecular design of copolymers bearing catechol- and Li+ ion-conducting anionic pendants endow redox-active polymers (RAPs) with ultrarobust electrochemical energy storage features when combined to carbon nanotubes a...
Poly(ionic liquid)s (PILs) have attracted considerable attention as innovative single-ion solid polyelectrolytes (SPEs) in substitution to the more conventional electrolytes for a variety of electrochemical devices.

Ion mobility-mass spectrometry (IM-MS) has emerged as a powerful separation and identification tool to characterize synthetic polymer mixtures topologies (linear, cyclic, star-shaped,…). Electrospray coupled IM-MS already revealed the coexistence of several charge state-dependent conformations for single state biomolecules with strong intramolecular interactions, even when limited resolving power instruments were used. For polymers, sample's polydispersity allows observation chain lengths. A...
