摘要

•A methyl-naphthyl functionalized cyclam (N-MNC) was self-assembled on gold electrodes.•The proton conductivity of the N-MNC film was brought out by EIS and by CV.•The ion-exchange resistance of the film decreased when metallic concentration increases.•The proton-exchange anodic peak increased when metallic concentration increases.•The highest sensitivity was obtained for Ni2+ and Fe3+, with a detection limit of 10−8M.
