Abstract
Provided is a compound having a wide temperature range exhibiting liquid crystallinity and excellent precipitation suppression and solubility; and a polymerizable composition, a cured product, an optical film, a polarizing plate, and an image display device, each using the compound. The compound is represented, for example, by Formula (1) or (2).
Claims30
A compound represented by Formula (1),
- in Formula (1),
- A1 represents an aromatic ring which may have a substituent or an alicyclic ring which may have a substituent,
- Cy represents a 1,4-cyclohexylene group which may have a substituent, and the two Cy's may be the same as or different from each other,
- D1, D2, and D3 each independently represent a single bond, or a divalent linking group consisting of —O—, —CO—, —S—, —C(═S)—, —CR1R2—, —CR1═CR2—, —NR1—, or a combination of two or more thereof, and R1 and R2 each independently represent a hydrogen atom, a fluorine atom, or an alkyl group having 1 to 4 carbon atoms,
- SP1 and SP2 each independently represent a single bond, a linear or branched alkylene group having 1 to 12 carbon atoms, or a divalent linking group obtained by each independently substituting one or more of —CH2-'s constituting a linear or branched alkylene group having 1 to 12 carbon atoms with —O—, —CO—, —S—, —C(═S)—, —CR1R2—, —CR1═CR2—, or —NR1—, and R1 and R2 each independently represent a hydrogen atom, a fluorine atom, or an alkyl group having 1 to 4 carbon atoms,
- k represents an integer of 1 to 3, and in a case where k is 2 or 3, a plurality of A1's and D2's which are present in the formula may be the same as or different from each other,
- L1 and L2 each independently represent a monovalent organic group, and at least one of L1 or L2 represents a polymerizable group, and
- B2, B3, B5, B6, B7, and B8 each independently represent a hydrogen atom or a substituent, provided that in a case where at least one of B2, B3, B6, or B7 represents a substituent, the substituent does not include a ring structure.
