    摘要: Biphenyl compounds which may be used as components of chiral smectic liquid crystal compositions. have the formula:
    wherein X represents F, Cℓ, Br, CN or H; and when X represents F, Cℓ, Br or Cn, one of R¹ and R² is a C₄-C₁₈ alkyl group having a methyl branch and the other is a C₁-C₂₀ alkyl group, or, when X represents H, one of R¹ and R² represents an alkyl group having a methyl branch of the formula:
    (wherein n represents an integer of 3 or more) and the ohter of n¹ and n² represents a C₁-C₂₀ alkyl group.
