Mesogenic 4-acryloyloxy- and 4-(2,3-epoxypropoxy)phenyl 4-alkoxybenzoates

Procedures were developed which made it possible to synthesize in good yields homologs of 4-acryloyloxyphenyl 4-alkoxybenzoates (C3, C 5, C7, C8) and of 4-(2,3-epoxypropoxy)phenyl 4-alkoxybenzoates (C5, C7). The substituted phenylbenzoates obtained exhibit the enantiotropic nematic mesomorphism in a sufficiently wide temperature range. The studied compounds have absorption maxima in the near UV region and a high temperature of decomposition beginning.

Structure and properties of novel three-armed star-shaped liquid crystals

A series of novel three-armed star-shaped liquid crystals based on 1,3,5-trihydroxybenzene as a core and ω-[4-(p-alkoxybenzoloxy) phenoxycarbonyl]valeric acid as mesogenic arms were synthesized. Their chemical structures were confirmed by FTIR and 1

Optically active compound and photosensitive resin composition

A photoactive compound is used in combination with a photosensitizer, represented by the following formula (1): A?[(J)m?(X-Pro)]n ??(1) wherein A represents a hydrophobic unit comprising at least one kind of hydrophobic groups selected from a hydrocarbon group and a heterocyclic group, J represents a connecting group, X-Pro represents a hydrophilic group protected by a protective group Pro which is removable by light exposure, m represents 0 or 1, and n represents an integer of not less than 1. The protective group Pro may be removable by light exposure in association with the photosensitizer (especially, a photo acid generator), or may be a hydrophobic protective group. The hydrophilic group may be a hydroxyl group or a carboxyl group. The photoactive compound has high sensitivity to a light source of short wavelength beams, for resist application, therefore, the photoactive compound is advantageously used for forming a pattern with high resolution.

Study of activation energy and order of reaction of some liquid crystals

Liquid crystals of the type p-phenylene-di-p-n-alkoxy benzoate have been prepared. Kissinger isothermal decomposition method has been used for determination of activation energy values of liquid crystals. Kissinger's assessment for shape index of DTA peaks is used to find the order of reaction. There is no direct relationship between the carbon atoms in terminal methylene groups and Ea values. Order of reaction value decreases with increase in heating rate upto carbon atoms 10 in the terminal methylene group but beyond this the order increases or decreases.

1,1'-Disubstituted Ferrocene-Containing Thermotropic Liquid Crystals of Structure 5-C5H4)COOC6H4XC6H4OCnH2n+1>2> (X=OOC or COO). Influence of the Orientation of the Central Ester Function on the Mesogenic Properties

The two series I and II of 1,1'-disubstituted ferrocenes which differ by the direction of the ester function included the rigid organic part were synthesized and their liquid crystal properties examined.These latter were found to be strongly dependent on the orientation of the connecting ester group and on the alkyl chain.
