(S)-2-(4'-Octyloxybiphenyl-4-carboxy)-5,5-dipropyl-δ-valerolactone showed interesting properties as the chiral dopant for ferroelectric liquid crystals (FLCs).The FLC mixture containing only 2percent by mol of this compound exhibited the magnitude of spontaneous polarization (Ps) as large as 9.6 nC/cm² and the response time as fast as 75 μs at 25 deg C in the electric field of +/- 5 V/μm.
