## Abstract Ionic liquids were synthesised that consisted of two methylimidazolium rings joined by a spacer 1β12 carbon atoms in length. The bis(triflic)imides with spacer β€C~4~ were solids; the others were liquid at room temperature. The polarity of the dication liquids and their performance in th
## Abstract Specific textures and their temperature transformations in large temperature interval for the chiral smectic C\* mesophase of new liquid crystalline materials, synthesized by our group, have been investigated in detail. Temperature dependences of the pitch of helical structure of the sm
