Abstract: front page image
(EN)Laterally cyano-substituted terphenyls of formula (I), wherein R?1¿ and R?2¿ are independently selected from hydrogen or C¿1-15? alkyl, alkoxy, or alkyl or alkoxy in which one or more CH¿2? groups are replaced by O, COO, OOC, CHX, CX¿2?, CH=CX, CX=CH, CX=CX, where X is fluorine or chlorine, CRCN where R is alkyl, or C=C, or in which a terminal CH¿3? of the said alkyl or alkoxy chain is replaced by CF¿3?, n is 0 or 1, and the CN and F (if present) substituent are independently located in any of the available substitution positions. Liquid crystal materials containing these terphenyls are also described.
