Teoh, Wei-Jing;Tun Nur Iskandar, Nur Amanina Juniasari;Yeap, Guan-Yeow;Kaneko, Kazuyoshi;Shimizu, Akio;Ito, Masato M. research published 《 Experimental and computational studies of laterally ethoxy Schiff base-ester liquid crystalline magnets》, the research content is summarized as follows. A series of liquid crystals 4-X-(3′-ethoxy-4′-alkyoxyphenyimino)anilines I (X = Me, MeO, Cl; n = 7, 8) with elongated mol. axis through the introduction of alkoxy chains containing different substituents was synthesized. The thermal-optical behaviors of these organic magnets were characterized by differential scanning calorimetry and polarized optical microscopy. Elemental anal., FT-IR and 1H-NMR were employed to elucidate the mol. structures of the target compounds Exptl. data show that the nematic phase temperature range increases in the order of CH3 < Cl < OCH3. The laterally ethoxy Schiff base-ester liquid crystal with the most electroneg. Cl atom is presumed to outweigh both analogs containing CH3 and OCH3, leading to the highest clearing temperature (Tc) value, but the present work proved that the presence of the O atom from OCH3 is inclined to orientate in a parallel arrangement that increases the length-to-breadth ratio and the polarizability of the mol. Computational studies on the different substituents against its kinetic stability were carried out based on the variation in the energy value of HOMO-LUMO gap (ΔEgap). A relationship between the energy gap and the substituents under the present study shows that when the ΔEgap increases from OCH3 < Cl < CH3, the chem. reactivity decreases, leading to the lowering of the clearing temperature
