Cheng, Zihui published the artcileInfluence of linkage and terminal group on the liquid crystalline and helical twisting behaviors of cholesteryl esters, Formula: C15H14O3, the publication is Liquid Crystals (2011), 38(7), 803-812, database is CAplus.
Three series of cholesteryl esters with different linkages and terminal groups were synthesized and characterized. All esters except cholesteryl 6-bromohexanoate can exhibit thermotropic liquid crystalline phases in certain temperature regions. The insertion of a 4-phenoxy and a 4-biphenylyloxy group in the ester can increase the mol. length, broaden the whole mesophase width and heighten the clearing temperature The increasing mol. length can enforce the layered arrangement in series A and B (resulting in a monolayer smectic A phase), while destroying the layer stacking in series C (resulting in a suppressed or absent intertwined smectic A phase). Meanwhile, the mol. structure played an important role in the molar helical twisting power and its temperature dependence. The target compounds thus formed included cholesterol esters, (3β)-cholest-5-en-3-ol 3-[6-(2-naphthalenyloxy)hexanoate] and (3β)-cholest-5-en-3-ol 3-[6-[(4′-cyano[1,1′-biphenyl]-4-yl)oxy]hexanoate] and corresponding benzoate and biphenylcarboxylate derivatives
