Abstract

Abstract

　A novel poly(ionic liquid) which can be used as a carbon precursor was synthesized using a one-pot reaction using 1,2-dimethylimidazole and epichlorohydrin as starting materials. The unique features of this poly(ionic liquid) include: no additional initiator is required; anions can be metathesized to regulate the micropore size of the carbonaceous materials. Carbonaceous materials derived from the poly(ionic liquid) with chloride anions (Cl^-) as counter ions have a low surface area of 47m²/g. However, by replacing Cl^- with a bulky bis(trifluoromethylsulfonyl)imide (TFSI^-) anion, the carbonaceous materials produced have a high surface area of 595m²/g, while replacing Cl^- with dicyanoimide (N(CN)2^-) anion results in a reduced surface area of 30m²/g.
