New mesogens with a fluoro-substituted bent core

Synthesis and characterization of side-chain liquid crystalline polysiloxanes containing α-terpineol in mesogenic group

“…In some cases the 1,4-cyclohexyl ring or 2,5-disubstituted 1,3-dioxane is also used to replace one of the phenylenes [9]. Over the past few years several modifications have been done on mesogenic group, as well as new meogens have been synthesized, which includes phenolphthalein as a part of the mesogen [10], 1,3,4-thiadiazole ring as mesogen [11], banana-shaped mesogen [12], disubstituted ferrocene ester as mesogen [13], [2.2]parafluoroalkyl-substituted carbohydrate-based mesogen [14], new mesogens with fluoro-substituted bent core [15], new smectic C mesogens containing a benzyl, phenylethyl or phenylpropyl moiety [16], new sheet-shaped mesogen based on 1,3,5-triazines [17], mesogens with cyclopentanone moiety [18] and others: the list is only illustrative but never exhaustive.…”
