Modulating the Conductivity of Light-Responsive Ionic Liquid Crystals
In this work, we describe the phase behaviour and the dielectric and conductivity response of new light-responsive ionic liquid crystals, ILCs, which can be applied as controllable electrolytes. The materials include two different dicationic viologens, the asymmetric 6BP18 and the symmetric EV2ON(Tf...

The 5%-CNAzO14/Ev2ON(Tf)2 mixture displays direct current conductivities in the 10-7 Scm-1 range, which can be increased by a two-fold factor upon the irradiation of UV light at 365 nm.
