1-Ethyl-3-methylimidazolium dicyanamide EMImN(CN)(2) and S-ethyltetrahydrothiophene dicyanamide EThN(CN)(2) physically confined into mesoporous silica gel with pore sizes of 6-8 nm (IL-sg) were synthesized according to a proper sol-gel process. Greatly enhanced fluorescence emissions of dicyanamide based ILs after being confined were exhibited. (C) 2008 Elsevier B.V. All rights reserved.
