T. Kusumoto et al., SYNTHESIS AND ELECTROOPTICAL PROPERTIES OF 3-FLUOROALKYL-SUBSTITUTED PHENYLPYRIMIDINES AS CHIRAL DOPANTS FOR FERROELECTRIC LIQUID-CRYSTALS, Chemistry Letters, (7), 1993, pp. 1243-1246
Starting with (R)-1,2-epoxyalkanes, -alkyloxy)-2-[4-(3-fluoroalkyl)-ph
eynl]pyrimidines and -5-(3-fluoroalkyl)-2-(4-alkyloxyphenyl)pyrimidine
s were synthesized and shown to be good chiral dopants for achieving f
ast response of ferroelectric liquid crystals mixtures.
