Six new symmetrical three-armed star-shaped liquid crystals comprising phloroglucinol (1,3,5-trihydroxybenzene) as a core center and three Schiff base ester as the mesogenic arms have been synthesized. Their molecular structures were supported by spectros

Exploration of new ruthenium-based sensitizers for dye-sensitized solar cell (DSC) applications requires an easy access to multifunctionalized ligands for efficient screening of sensitizers' properties. Based on the Horner-Emmons-Wadsworth reaction, a convenient synthetic route for the extension of the π-system on 4,4′-disubstituted-2,2′-bipyridines was used to develop a novel series of functionalized 2,2′-bipyridine ligands with either electron-withdrawing or donating end-capping group. 1H NMR spectroscopy revealed that all the new bipyridyl ligands were obtained exclusively in their fully E isomers.

, (2008/06/13)
Novel ferroelectric liquid crystals exhibiting a chiral smectic C phase and liquid crystal compositions containing the same are provided, which liquid crystals are substituted biphenyl esters expressed by the general formula STR1 wherein R1 * represents an optically active alkyl group of 4 to 18 carbon atoms; STR2 represents STR3 or STR4 Z represents R2, R2 CO or R2 COO wherein R2 represents an alkyl group or an alkoxy group each of 1 to 18 carbon atoms; and X and Y each represent hydrogen atom (H), bromine atom (Br), chlorine atom (Cl), fluorine atom (F) or cyano group (CN), and either one of X or Y is always hydrogen atom.
