Detection of Chiral Perturbations in Ferroelectric Liquid Crystals Induced by an Atropisomeric Biphenyl Dopant

The atropisomeric dopant 2,2‘,6,6‘-tetramethyl-3,3‘-dinitro-4,4‘-bis[(4-nonyloxybenzoyl)oxy]biphenyl (1) induces a ferroelectric SmC* phase when doped into the SmC liquid crystal hosts 2-(4-butyloxyphenyl)-5-octyloxypyrimidine (PhP1) and (±)-4-[(4-methylhexyl)oxy]phenyl 4-decyloxybenzoate (PhB). The...

Zusammenfassung:	The atropisomeric dopant 2,2‘,6,6‘-tetramethyl-3,3‘-dinitro-4,4‘-bis[(4-nonyloxybenzoyl)oxy]biphenyl (1) induces a ferroelectric SmC* phase when doped into the SmC liquid crystal hosts 2-(4-butyloxyphenyl)-5-octyloxypyrimidine (PhP1) and (±)-4-[(4-methylhexyl)oxy]phenyl 4-decyloxybenzoate (PhB). The propensity of dopant 1 to induce a spontaneous polarization (polarization power) is much higher in PhP1 than in PhB (1555 nC/cm2 vs
