The influence of flexible spacer and the chirality of the core on the formation of chiral nematic phase of symmetric dimers containing trifluoromethyl terminal

Liquid crystalline dimers containing a cholesteryl benzoate unit: smectic phase, chiral nematic phase and blue phase

“…The dimer, on the other hand, is considerable and would exhibit phase transition behaviors that are fundamentally different from those of liquid crystals with low molar mass in the classical sense. [4][5][6][7] Liquid-crystalline dimers are divided into symmetric dimers 8 and non-symmetric dimers. [9][10][11][12][13][14] Symmetric dimers show abundant smectic polymorphisms.…”
