Abstract

Cyclic delocalized cations joined together by spacer groups, with anions of equal number to cations to maintain charge neutrality, are disclosed. These spacer groups may be organic or inorganic in origin and may vary in length. The spacer groups may be saturated, containing single bonds, or may be unsaturated, containing double and triple bonds. With appropriate design these materials can have melting and glass transition temperatures below, around, and above room temperature. The lyophobic character of these materials may be adjusted, providing unique properties. These materials are well suited for use as electrolytes, lubricants, solvents for extractions and for running reactions, biphase catalysis media, media for electroluminescent devices.
