We have synthesized new phenylacetylene-based liquid crystals containing a cyclohexyl or cyclohexylethyl group and evaluated their physical properties in order to develop a range of materials having high value of birefringence. The cyclohexyl-contain

We have synthesized and investigated new 3-ring phenylacetylene liquid crystals with high birefringence values (Δn) to improve the nematic temperature range while retaining a high optical anisotrop...

We have synthesized and evaluated the physical properties of thiophenylacetylene and benzothiazolylacetylene derivatives in order to obtain higher Δn liquid crystals as compared with analogous phenylacetylene-based compounds. These new materials had

Two kinds of novel molecular materials with high optical anisotropy were synthesized and evaluated. Liquid crystalline phenylacetylene derivatives, which have mesogen of a 1,4-Bis(phenylethynyl)benzene, not only showed high δn but also were stable f

The amine-catalyzed Knoevenagel reactions of aldehydes and active methylene compounds containing two activating groups were found to involve many reversible steps, and the diastereomeric intermediary condensation compounds yielded thermodynamically s

The stereochemistry of the mechanism of the amine-catalyzed Knoevenagel reaction has been studied. Simple treatment of methyl arylsulphinylacetate (1) and aldehydes (2) with a catalytic amount of a secondary amine produced thermodynamically stable E-
