Abstract
A compound has an excellent rate of change in HTP caused by exposure. A liquid crystal composition is formed of the compound. A cured product, an optically anisotropic body, and a reflective film can be obtained by curing the liquid crystal composition. The compound is represented by General Formula (1):
Claims15
A compound represented by General Formula (1),
- in General Formula (1), a portion where a solid line and a broken line are parallel to each other represents a single bond or a double bond,
- in General Formula (1) X1 to X8 each independently represent a hydrogen atom or a monovalent substituent, provided that at least one of X1, X3, X5, or X7 and at least one of X2, X4, X6, or X8 represent a substituent selected from the group consisting of a substituent including a group represented by General Formula (2A) and a substituent including a group represented by General Formula (3A),
- in General Formulae (2A), Z represents a single bond or —O—, Y1 and Y2 each. independently represent a hydrogen atom or a hydrocarbon group not including an aryl group, and *1 represents a bonding position, and R1 represents a hydrogen atom or a substituent, and the group represented by General Formula (2A) has Y1 and Y2 on the same side with the double bond specified h General Formula (2A) as an axis,
- in General Formula (3A). :A represents a hydrocarbon ring group which may have a substituent or a heterocyclic group which may have a substituent, Y1 and Y2 each independently represent a hydrogen atom or a hydrocarbon group not including, an aryl group, and *1 represents a bonding position, and R3 represents a hydrogen atom or a substituent, and the group represented by General Formula (3A) has Y1 and Y2 on the same side with the double bond specified in General Formula (3A) as an axis, and
- in General Formula (1), X1 and X2 may be linked to each other to form a ring.
