Electroclinic effect in chiral SmA* liquid crystals induced by atropisomeric biphenyl dopants: Amplification of the electroclinic coefficient using achiral additives
The atropisomeric compound (R)-2,2′,6,6′-tetramethyl-3, 3′-dinitro-4,4′-bis[(4-nonyloxybenzoyl)oxy]biphenyl ((R)-1) was doped in the achiral liquid crystal hosts 2-(4-butoxyphenyl)-5- octyloxypyrimidine (2-PhP) and 4-(4′-heptyl[1,1′-biphen]-4-yl)-1- hexyl
