Osman, Maged A. published an article in Zeitschrift fuer Naturforschung, Teil A: Physik, Physikalische Chemie, Kosmophysik. The title of the article was 《Molecular structure and mesomorphic properties of thermotropic liquid crystals. II. Terminal substituents》.Category: esters-buliding-blocks The author mentioned the following in the article:
The effect of terminal polar nonpolar substituents on the thermodn. stability of the mesophase is discussed. Mesomeric and steric effects influence the packing of the mols. and consequently the clearing point. It is necessary to consider the effect of substituents in connection with the nature of the rigid core. The influence of mol. association and conformational equilibrium on the stability of the mesophase is described. Isolated electron densities lead to repulsions between neighboring mols., thus destabilizing the mesophase and the layered structure if present.4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9Category: esters-buliding-blocks) was used in this study.
4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9) belongs to esters. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. Category: esters-buliding-blocks
