摘要： Novel derivatives of cyclic and acyclic terpenoid alcohols, having general formula (I) X-(CO)n-O-T1, where n = O or 1, T1 is a terpenoid group and X is a combination of cyclic groups, eg phenyl, cyclohexyl and pyrimidyl. X preferably contains up to three cyclic groups. Preferred derivatives are esters of cyclic terpenoid alcohols, eg menthol, borneol and isopineocampheol, eg formula (II) (-)-menthol. Ferroelectric smectic liquid crystal mixtures and devices containing these derivatives as chiral dopants in a tilted smectic host are also described. The properties of various other derivatives of terpenoid alcohols of formula (I) are also described, eg those of neomenthol, isolongifolol, fenchol, carveol, myrthenol, nopol, citronellol, perilla alcohol and dihydrocitronellol.

摘要： Ferroelectric smectic liquid crystal mixtures are provided consisting of two constituents; a smectic host and another containing a chiral compound in which rotation of the chiral centre relative to the molecular core is sterically hindered, so that the chiral compound induces a high Ps in the mixture. A preferred class of chiral compounds is those derived from naturally occurring compounds with chiral groups, especially alpha-hydroxycarboxylic acids, amino acids and terpenoids, e.g. with chiral groups (I), (II), (III). The chiral group is incorporated into a compound containing a mesogenic combination of groups, e.g. with chains of cyclic groups and some mesogenic combinations are described.

摘要： Novel compounds suitable for use as components of a ferroelectric smectic liquid crystal composition, which contain two or more chiral centers derived from optically active alpha-hydroxy carboxylic acids, secondary alcohols, and terpenoid alcohols. These units are combined with a mesogenic combination of cyclic groups. Preferred compounds contain two or more lactate groups, lactate and 2-octyl groups, or lactate and terpenoid groups in combination with phenyl groups. Ferroelectric smectic liquid compositions containing these compounds, and a device using them are also described.

摘要： Compounds which may be used as a dopant or host in a ferroelectric chiral smectic liquid crystal mixture. The compounds are characterised in that they are derivatives of an X-hydroxy carboxylic acid and contain the chiral unit (I), in which Ro may be alkyl, alkoxy, halogen, formula (II), where b may be 0 to 3 and the phenyl ring may be substituted, and a is 0 or 1. The chiral unit is combined with a range of mesogenic combinations of groups. Lactic acid derivatives are described in detail (i.e. Ro = methyl) together with various preparative routes, for example the compound formula (III), which has dopant properties in a range of hosts.
