In 2019,Chemistry – A European Journal included an article by Walker, Rebecca; Pociecha, Damian; Storey, John M. D.; Gorecka, Ewa; Imrie, Corrie T.. HPLC of Formula: 2623-87-2. The article was titled 《The Chiral Twist-Bend Nematic Phase (N*TB)》. The information in the text is summarized as follows:
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 In the part of experimental materials, we found many familiar compounds, such as 4-Bromobutanoic acid(cas: 2623-87-2HPLC of Formula: 2623-87-2)
4-Bromobutanoic acid(cas: 2623-87-2) belongs to carboxylic acids. The chief chemical characteristic of the carboxylic acids is their acidity. They are generally more acidic than other organic compounds containing hydroxyl groups but are generally weaker than the familiar mineral acids (e.g., hydrochloric acid, HCl, sulfuric acid, H2SO4, etc.).HPLC of Formula: 2623-87-2
