Synthesis of New Chiral Dopants Derived from 2-Phenylpropanoic Acid Derivatives for Nematic Liquid Crystals

Bulletin of the Chemical Society of Japan (Impact Factor: 2.21). 01/2001; 74(11):2219-2222. DOI: 10.1246/bcsj.74.2219


New chiral dopants for nematic liquid crystals were synthesized using optically active 2-phenylpropanoic acid derivatives. The magnitude of the helical twisting power (HTP) was largely influenced by the terminal group of the asymmetric frame and the core structures. (S)-1-[4-(trans-4-Butylcyclohexyl)phenyl]-2-phenylpropane-1-one showed a large HTP value (20.4 μm -1). The relationship between the HTP and the molecular structures of the chiral dopants is discussed.
