The invention relates to compounds of formula (I): insert Formula (I) here wherein R1and R2are each independently selected from the group: H, F, Cl and CH3; n1 and n2 are each independently integers 3 to 20; q and r are each independently integers 0, 1 or 2, with the proviso that q + r is ≥ 1; D is a divalent chiral radical selected from the group: (D1-D4) wherein R3 is a C1 to C6 straight or branched chain alkyl group; and each B1and B2 is a divalent radical independently selected from the group: R4-substituted-1,4-phenyl, wherein R4 is H,-CH3 or -OCH3, 2,6-naphthyl; and 4,4'-biphenyl; with the provisos that when q + r = 3, at least one of B1 and B2 is R4-substituted-1,4-phenyl; and when q + r = 4, at least two of B1 and B2 are R4-substituted-1,4-phenyl. The invention further relates to liquid crystal compositions comprising compounds of formula (I) and polymer networks derived from the polymerization of the liquid crystal compositions.
Novel non-symmetric chiral twin liquid crystals possessing two identical chiral moieties at both peripheral ends: Highly chirality-sensitive phases appeared between smectic and isotropic liquid phases
