dc.abstract.enA series of bent-core paramagnetic ionic liquid crystals derived from stable radicals, 6-oxoverdazyl and 1,4-dihydrobenzo[e][1,2,4]triazin-4-yl, and containing the N-methylimidazolium group were prepared and their mesogenic, magnetic and ion conductive properties were investigated. The ion pairs form fluid smectic phases above 100 °C, in which ionic layers are separated by paramagnetic layers. Ion conductivity for two selected derivatives is in a range of 10-5 –10-8 S cm−1 and activation energies Ea are about 1.5 eV. Magnetic susceptibility measurements (SQUID) of pristine solid samples revealed liquid-like molecular arrangement in the paramagnetic layers and weak antiferromagnetic interactions
