Physicochemical properties of nitrile-functionalized d

Article Abstract:

The preparation and characterization of a series of ionic liquids (ILs) based on nitrile-functionalized imidazolium, pyridinium and quaternary ammonium as cations and chloride and tetrafluoroborate, hexafluorophosphate, dicyanamide, and bis(trifluoromethanesulfonyl)imide as anions is presented. The physicochemical properties are comparatively studied and the results have shown that the incorporation of a CN group to a cation result in remarkable changes in these properties.

Vibrational Stark effect probes for nucleic acids

Article Abstract:

The Stark spectroscopy of structurally diverse nucleosides is examined in order to explore the use of vibrational Stark effect (VSE) in nucleic acids. Nitrile-deoxyuridine and nitrile-deoxyguanosine can be used for the major and minor grooves of DNA.
