Abstract

Brønsted acid ionic liquids were successfully applied to the electrochemical synthesis of polyaniline films on platinum electrode surfaces by using cyclic voltammetry. The scanning electron micrographs showed distinct changes in morphological structures. The films exhibited quite dense packing and good ordering of polymer dendrite as compared with those prepared using conventional hydrochloric acid, indicating that Brønsting acid ionic liquids might be promising alternatives to dual medium‐dopants in the synthesis of conducting polymers.

## Abstract Cyclodehydration of diethylene glycol using various Brønsted acidic ionic liquids as dual solvent‐catalysts was studied for the first time. Better results were obtained in the presence of 1‐butyl‐3‐methylimidazolium hydrogen sulfate ([SPmim]HSO~4~) than other Br?nsted acidic ionic liqui
