| titleOfInvention | Dichroic azo dye, liquid crystal composition containing the same, and liquid crystal element using the composition |
| abstract | A dichroic dye represented by formula (I) or (II):n n wherein R¹ and R² each represent a hydrogen atom or a nonionic substituent; X¹ and X¹ each representn n Z¹, Z², Z³, Z⁴, Z⁵, Z⁶, Z⁷, Z⁸, Z⁹, Z¹⁰, Z¹¹, and Z¹² each represent a hydrogen atom, a halogen atom, a methyl group or a methoxy group; Z¹ and Z², Z⁴ and Z⁵, Z⁷ and Z⁸, or Z¹⁰ and Z¹¹ may be connected to each other to form an aliphatic, aromatic or nitrogen-containing aromatic ring; and n and m each represent 0, 1 or 2n n wherein R¹¹, R¹², R¹³, and R¹⁴ each represent a hydrogen atom, an alkyl group, an alkoxyalkyl group, a substituted or unsubstituted aralkyl group or a fluoroalkyl-substituted alkyl group, provided that a compound in which R¹¹ is a hydrogen atom and R¹² is a substituted or unsubstituted aralkyl group and a compound in which R¹³ is a hydrogen atom and R¹⁴ is a substituted or unsubstituted aralkyl group are excluded; R¹¹ and R¹², or R¹³ and R¹⁴ may be connected to each other to form a nitrogen-containing aliphatic ring; Z²¹, Z²², Z²³, Z²⁴, Z²⁵, Z²⁶, Z²⁷, Z²⁸, Z²⁹, Z³⁰, Z³¹, and Z³² each represent a hydrogen atom, a halogen atom, a methyl group or a methoxy group; Z²¹ and Z²², Z²⁴ and Z²⁵, Z²⁷ and Z²⁸, or Z³⁰ and Z³¹ may be connected to each other to form an aliphatic, aromatic or nitrogen-containing aromatic ring; R¹¹ and Z²³, R¹² and Z²¹, R¹³ and Z³², or R¹⁴ and Z³¹ may be connected to each other to form a nitrogen-containing aliphatic ring; and p and q each represent 0, 1 or 2, provided that p and q are not simultaneously 0. nThe dichroic dyes (I) and (II) exhibit excellent dichroism and can be prepared from 2,2'-ditrifluoromethylbenzidine having no toxicity, such as mutagenicity. |
