, p. 15 - 22 (2001)
A new series of non-symmetrical dimeric compounds containing two distinct mesogenic groups, 4-(4'-benzyloxy)biphenyl cholesteryl alkanedioates, was prepared in our laboratory. In addition, two symmetrical dimers, dichoresteryl decanedioate and di[4-(4'-be

Paragraph 0132, (2021/07/17)
The present invention provides a compound represented by formula (i), a liquid crystal composition using the compound, and a liquid crystal display device using the liquid crystal composition. The compound represented by formula (i) has a partial structure Ki1 represented by any of general formulas (K-1) to (K-17) and further has ring B having at least two P-Sp- groups. Therefore, when used for a liquid crystal composition, the compound adsorbs to substrates sandwiching the liquid crystal composition (liquid crystal layer) and allows liquid crystal molecules to be held such that they are aligned in a vertical direction without a PI layer, and improved alignment stability and low-temperature storage stability can be achieved.

, p. 81003 - 81012 (2015/10/12)
New mesogenic compounds exhibiting unique, so called orthoconic, behavior at the synclinic smectic SmC? phase have been obtained. The newly synthesized compounds belong to two chiral homologous series: 4′-[ω-(2,2,3,3,4,4,4-heptafluorobutoxy)alkoxy]bipheny
Towards New Oligomesogenic Phosphonic Acids as Stabilizers of Nanoparticles Colloids in Nematic Liquid Crystals
Prodanov, Maksym F.,Diakov, Maksym Y.,Vlasenko, Ganna S.,Vashchenko, Valerii V.
, p. 1905 - 1910 (2015/08/06)
Several synthetic strategies for the construction of linear and branched oligomesogenic phosphonic acids are examined, which differ in the method of building the key bimesogen unit. An efficient synthetic approach to the most promising compounds employs regioselective Kumada cross-coupling between [11-(4′-pentylbiphenyl-4-yl)undecyl]magnesium bromide and 4-(11-bromoundecyl)-4′-iodobiphenyl as the key step. Preliminary studies on the ability of the new ligands to stabilize nanoparticles colloids in nematic liquid crystals are undertaken for the example of quantum dots.
Membrane-length amphiphiles exhibiting structural simplicity and ion channel activity
