Erratum: Evaluation Of proton conductivity of sulfonated polyimide/dihydroxy naphthalene charge‐transfer complex hybrid membranes

Abstract

Graphical Abstract:Polymer coupling reactions are some of the most challenging chemical transformations due to low end-group concentration, steric hindrance, and decreased reactivity. Thiolyne chemistry is shown to be a near-quantitative and selective strategy for the coupling of preformed polymers to give block and graft copolymers. With aromatic alkynes under a wide range of conditions, specific monoaddition is achieved with efficiencies surpassing those of traditional thiol-ene chemistry.This text was incorrect and should be:The sulfonated polyimide (SPI) / dihydroxynaphthalene (DHN) charge-transfer (CT) complex hybrid films include CT complexes, which might work as electronic conductors, and sulfonic acid units, which could work as proton conductors. From impedance results, it was confirmed that proton transfer dominantly occurred in the CT complex hybrid films. Activation energy of proton conductivity of the CT films showed approximately the same values of that of Nafion 212.The publishers apologize for any inconvenience that may have occurred.
