Abstract: The interplay between liquid crystals and nanostructures is fascinating as well as challenging to understand the dispersion effect of nanomaterials onto liquid crystals. Herein, we report the dispersion of zero-dimensional silver nanoparticles (Ag NPs) in two discotic liquid crystals. The columnar stacks of 1,5-dihydroxy-2,3,6,7-tetrakis(3,7-dimethyloctyloxy)-9,10-anthraquinone (RTAQ) and 2,3,6,7,10,11-hexabutoxytriphenylene (HAT4) discotics are self-assembled with silver nanoparticles in a hexagonal manner at different weight concentrations. The dispersion of NPs reduces the lattice parameter, intracolumnar packing and increases electrical conductivity by the order of four to five in HAT4 DLC.
