The Diels–Alderreactions of 1-(p-substituted phenyl)buta-1,3-dienes with methylacrylate are shown to give 2-arylcyclohex-3-enecarboxylates, irrespective of the nature of the aryl-substituent, but the steric course of the reaction is affected by the substituent. Similar results were obtained with 1-aryl-2,3-dimethylbuta-1,3-dienes.
A liquid crystal composition which prevents production of an alignment defect of a liquid crystal compound and also has excellent storage stability during dissolution in a solvent is provided. The liquid crystal composition is suitable for constituting a retardation film capable of favorable circular polarization conversion. The liquid crystal composition includes a polymerizable liquid crystal compound having 3 or more ring structures in the main chain, and aluminum. A content of the aluminum is 1 ppm or more and 170 ppm or less relative to the polymerizable liquid crystal compound.
A liquid crystal composition containing a polymerizable liquid crystal compound (A) having 5 or more ring structures in its main chain and a polymer (B) of the polymerizable liquid crystal compound (A) having 5 or more ring structures in its main chain, which inhibits occurrence of an orientation defect of a liquid crystal compound and exhibits excellent storage stability when dissolved in a solvent is provided.
A compound capable of suppressing the occurrence of alignment defects and lowering the phase transition temperature of a liquid crystal composition without impairing optical characteristics is provided. In particular, a compound represented by formula (A) is provided in which the variable groups are as defined in the specification.
