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.

salts are liquids at room temperature, at which some salts based on [NO3]− and [NTf2]− ions exhibit organicplasticcrystal behaviors, and all the saccharin‐based salts display relatively high refractive indices (1.442–1.594). In addition, some ionicliquids with the [NTf2]− ion exhibit peculiar spectroscopic characteristics in FTIR and UV/Vis regions, whilst those salts based on the [DCA]− ion show
