1. one kind comprises negatively charged ion and cationic ionic liquid, it is characterized in that described positively charged ion is the cationic nitrogenous of formula (I):

  • N +HRR′


    (I) Wherein R is for choosing wantonly by one or more alkyl that are selected from following substituting group replacement;

    nitrogen-containing functional group (comprises itrile group, the alkaline nitrogen-containing functional group that nitro is amino or other), sulfydryl, alkylthio, alkylsulfonyl, thiocyanate ion, isosulfocyanate radical, azido-, diazanyl, halogen, optional by one or more ehter bonds or thioether bond alkyl at interval, alkoxyl group, thiazolinyl, hydroxyl, carbonyl (comprising aldehydes or ketones), carboxyl, borate, the amino of silyl and replacement (alkyl monosubstituted amino for example, dialkyl amido or alkyl amido);

    WithR '"'"' and R " can be identical or different, represent H or R separately;

    Perhaps R, R '"'"' and R " in any two or three can be joined together to form cyclic group with N.
