A new class of liquid crystals was formed with N-heterocycles as the terminal group, such groups as a 3,4-difluoropyrrole, 3,3,4,4- tetrafluoropyrrolidine, or pyrrolidine. Their properties were modified by varying the terminal heterocycles and/or the leng

A new class of benzodioxocycloalkane-based (C8-C10) liquid crystals were prepared. The impact of ring (C8-C10) as end group was investigated. The 8-9 membered ring derivatives, 3a-3b, exhibited the nematic phases (N). The mesomorphic behaviors were weakened with increasing the size of the ring. For the ?uorinated medium ring (C 8-C10) 3d-3f, it was found only the fluorinated ten membered ring 3f showed the LC phases behaviours. Modification of the ring size with different length alkyl groups and variation of the alkyl to polyfluoroalkyl markedly influenced the properties of these compounds.

A series of new 3,4-difluoropyrrole-, 3,3,4,4-tetrafluoropyrrolidine-based tolan liquid crystals resulted from palladium-free Sonogashira coupling reactions of 1-(4-iodophenyl)-3,4-difluoropyrrole, 1-(4-iodophenyl)-3,3,4,4- tetrafluoropyrrolidine with terminal phenyl acetylenes. These new compounds exhibit typical nematic and smectic phases, good thermal stabilities, and high clearing points in comparison to the liquid crystal phase of 3,4-difluorobenzene-based tolan. These encouraging results lead us to believe this class of compounds could be used as new liquid crystalline materials. It is possible that the fluorinated N-heterocycles, 3,4-difluoropyrrole and 3,3,4,4-tetrafluoropyrrolidine, could replace the expensive 2,3-difluorobenzene, 3,4-difluorobenzene, and 3,4,5-trifluorobenzene components in the tolan core structure to form promising liquid crystalline materials.

A new class pyridinium-based liquid crystals with an extended fluorinated pyrrolidine were synthesized. These compounds show a wide mesophase range and are stable to high temperatures after an introduction of a fluorinated pyrrolidine to the terminal end.
