Formula: C8H15BrO2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 8-Bromooctanoic acid, is researched, Molecular C8H15BrO2, CAS is 17696-11-6, about The Chiral Twist-Bend Nematic Phase (N*TB). Author is Walker, Rebecca; Pociecha, Damian; Storey, John M. D.; Gorecka, Ewa; Imrie, Corrie T..
The twist-bend nematic, NTB, phase has been observed for chiral materials in which chirality is introduced through a branched 2-methylbutyl terminal tail. The chiral twist-bend nematic phase, N*TB, is completely miscible with the NTB phase of the standard achiral material, CB6OCB. The N*TB phase exhibits optical textures with lower birefringence than those observed for the achiral NTB phase, suggesting an addnl. mechanism of averaging mol. orientations. The N*-N*TB transition temperatures for the chiral materials are higher than the NTB-N transition temperatures seen for the corresponding racemic materials. This suggests the double degeneracy of helical twist sense in the NTB* phase is removed by the intrinsic mol. chirality. A square lattice pattern is observed in the N* phase over a temperature range of several degrees above the N*TB-N phase transition, which may be attributed to a non-monotonic dependence of the bend elastic constant
