Abstract
A green chemistry approach has been adopted for the synthesis of thirty-four new picolinium-based ionic liquids using microwave (MW) and ultrasound (US) irradiation as well as conventional thermal heating. Their structures were confirmed by FT-IR,
H NMR,
C NMR,
B NMR,
F NMR,
P NMR, mass spectra and elemental analyses. The antimicrobial profile of the novel ionic liquids was evaluated and the minimum inhibitory concentration (
) showed their moderate to low antimicrobial activity against eight types of human pathogens.
