摘要： The use of a mesogenic compound having a terminal end chain comprising carbon, oxygen, or sulphur, which has at least one pendent C1-4alkyl, C1-4alkoxy or a cycloalkyl ring, arranged no more than 6 atoms from the end of the chain either decreasing the melting point, increasing the clearing point, increasing the speed of switching and/or increasing the tilt angle of a liquid crystal mixture. Examples of such compounds are of formula (I) where M is a mesogenic core group, and X and Y are terminal groups, provided that at least one group X or Y is a group of sub-formula (i) where Z1, Z2, R1, R2, R3, R4, R5, R6, R7, s, q, m and n are as defined in the specification. Novel compounds of formula (I) are also described and claimed.

摘要： Polymeric compounds of general formula (I) where X, X1, X2 are independently straight or branched chain C1-16 alkyl, halogen and H; (a) is a suitable mesogenic group; Z=single covalent bond, oxygen CO2, OCO; n=1-20; Y=oxygen, CO2, OCO, CH2, CHOH, CH2O; m=3-10,000. The compounds are liquid crystal polymers useful in liquid crystal devices, sensors, and in non-linear optical devices. The compounds are prepared by polymerization of the oxitane monomer to obtain the side-chain liquid crystalline polyoxitane compound. In this way the mesogenic groups are spaced on every fourth carbon atom in the polymer chain allowing greater mobility for the mesogenic group.
