Provided are an alkoxysilane that is used as a material for liquid crystal alignment films or the like, and a method for producing said alkoxysilane. An alkoxysilane represented by formula (1), wherein a ring structure is linked by an amide bond. (In the formula, Z1, Z2 and Z3 each represent a linear or branched C1-4 hydrocarbon group or the like; Z4 represents H, a methyl group or the like; Y1 represents a single bond, -C(CH3)=CH- or the like; Cy1 represents a phenylene group or the like; Cy2 represents a phenylene group or the like; Z5 represents H, a linear or branched C1-18 hydrocarbon group or the like; a represents an integer of 1-18; m represents 1 or 2; and n represents 0, 1 or 2.)

In this work, twelve compounds: S(+)-4-4'-(4''-trans-n-alkylcyclohexyl)benzoates; S(+)-4-4'-(4''-trans-n-alkylcyclohexyl)benzoates, where alkyl = C5-C10 were synthesized.The effect of the alkyl c
The Liquid-Crystalline Properties of Copper(II) Complexes of β-Diketones
Thompson, Neil J.,Gray, George W.,Goodby, John W.,Toyne, Kenneth J.
, p. 109 - 132 (2007/10/02)
The preparation of several novel copper(II) complexes of β-diketones is described.Complexes of increasing molecular width have been prepared and the effect of molecular shape on the mesophase types and transition temperatures is discussed.All the liquid-crystalline complexes exhibit nematic mesophases (monotropic for three-ring ligands and enantiotropic for four-ring ligands) with one exception which shows a smectic A phase.The liquid crystalline properties of the ligands are also discussed with respect to the way in which their molecular geometry affects the type of mesophase formed.Keywords: Copper(II) complexes, β-diketones, metallo-mesogens

Treatment of the L-arabino- and L-lyxo-configurated glycals 1 and 7 with trimethylsilyl cyanide leads to the formation of the anomeric nitriles 2, 3 and 15, 17 respectively.The configurational assignments are based on hydrogenated products such as 6 or 8

The alkylation of benzene by 1-alkanoyl-2-chlorocyclohexanes and 1-alkanoyl-1-cyclohexenes leads to the formation of cis- and trans-4-alkanoyl-1-phenylcyclohexanes, the yields of which increase with increase in the reaction temperature. trans-4-Alkyl-1-phenylcyclohexanes were obtained from 4-alkanoyl-1-phenylcyclohexanes and also from the products from the reaction of 4-alkylcyclohexanones with phenylmagnesium bromide.Some mesomorphous derivatives of these hydrocarbons were synthesized.
