A series of monocationic and dicationic ionic liquids, in which each ionic liquid is associated with dicyanamide anion, are synthesized. The molecular structures of these compounds were identified by 1H-NMR, FT-IR and CHN analysis. Thermal behaviors of these ionic liquids were also investigated by thermogravimetry (TGA). The results suggested that all new ionic liquids have reasonable thermal s...

A composite polymer surface coated on a tin oxide offers dramatic improvement in the stability and sensitivity of voltammetric measurement of pyridostigmine bromide as compared to individual tin oxide, polyaniline or polypyrrole coated electrode. A linear current response was achieved with a detection limit of 1x10 M. The stability and morphology of the polymer surfaces were determined by therm...
