Abstract
(EN)
Compounds of formula (I) are provided which are particularly useful in STN devices, wherein n may be 0-5; m may be 1-5; p may be 1-9; q may be 0, 1 or 2; A1, A2 are independently chosen from 1,4-disubstituted benzene, 2,5-disubstituted pyrimidine, or 2,5-disubstituted pyridine, $i(trans)- 1,4-disubstituted cyclohexane, $i(trans)- 2,5-disubstituted dioxane; the aromatic rings may be laterally substituted with F, Cl, Br or CN; Z1 may be O, COO, OOC; Z2, Z3 are independently chosen from a direct bond, COO, OOC, C2H4, CH2O, OCH2, (a); provided that when Z1 is O and m is 1, 3 or 5, the carbon-carbon double bond configuration is E and when n is 2 or 4 the carbon-carbon double bond configuration is Z and when Z1 is COO or OOC and m is 0, 2 or 4, the carbon-carbon double bond configuration is E and when n is 1, 3 or 5, the carbon-carbon double bond configuration is Z.
