Title:
BIMESOGENIC COMPOUND
Document Type and Number:
Japanese Patent JP2017101034
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid crystal material having advantageous properties, good contrast, high level switch angle and quick response time even at low temperature for use in a flexoelectric display exhibiting high level switch angle and quick response time and achieving good uniform orientation over whole region of display cells without using a shearing process.SOLUTION: There is provided a bimesogenic compound represented by the formula (I). R-MG-Sp-MG-R(I), where Rand Rare each independently H, F, Cl, CN, NCS or a linear or branched alkyl group having C1 to 25 and substituted/unsubstituted by halogen or CN, one or more non-neighboring CH2 group may each independently be substituted so that O is not directly bound to each other by various connecting groups, MG1 and MG2 are each independently a mesogenic group, Sp is a C5 to 40 spacer group and may be substituted by one or more non-neighboring and non-terminal CH2 group or various connecting groups.SELECTED DRAWING: None
