Abstract The first research discusses the effect of terminal benzyloxy group on the mesomorphic properties of liquid crystalline materials developed from rod-like Schiff base. For this objective, a novel Schiff base liquid crystal family, specifically new series of Schiff base liquid crystals namely, (E)-4-(alkyloxy)-N-(4-(benzyloxy)benzylidene)aniline, In, are prepared by directly condensing 4-benzyloxybenzaldehyde with alkyloxy anilines, Scheme 1. Both Fourier transform infrared (FT-IR) and nuclear magnetic resonance (NMR) spectroscopy demonstrated that all the produced compounds possessed the aliphatic proton of the benzyloxy and terminal alkyloxy chain. The compounds’ molecular formulas and molecular structures were validated using elemental analysis, FT-IR measurements, and NMR spectroscopy. |
