Chirality driven mesomorphic behaviour difference: dichiral compounds containing two lactate groups was written by Wu, Xiaoqing;Wu, Limin;Guo, Yongmin;Li, Yi;Li, Baozong;Yang, Yonggang. And the article was included in Liquid Crystals in 2020.Quality Control of 4-Benzyloxyphenol The following contents are mentioned in the article:
Four compounds containing two lactate groups and one perfluorocarbon chain were designed and synthesized, whose chirality was tuned by changing the chirality of the lactic acid residues. (R,S)- And (S,R)- stereoisomers exhibited an enantiotropic SmA phase, while (R,R)- and (S,S)-stereoisomers exhibited an enantiotropic SmA phase and an enantiotropic SmCd* one. Therefore, the chirality of the compounds played an important role in the mesomorphic behaviors of the compounds The optical activity of these liquid crystals was dominated by the chirality of the lactate group near the core. (R)- And (S)- with one lactic acid residue and one perfluorocarbon chain exhibited only an enantiotropic SmA phase. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Quality Control of 4-Benzyloxyphenol).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Quality Control of 4-Benzyloxyphenol
