A homologous series of heterocycles, 6-methyl-2-(4-alkoxybenzylidenamino) benzothiazoles, were synthesized and characterized using FT-IR, 1H and 13C NMR and mass spectrometric analysis. Enantiotropic nematic phase was observed for sh

A new series of rod-shaped mesomorphic compounds, 6-methyl-2-(4-alkoxybenzylidenamino)benzothiazoles bearing a fused thiazole ring and imine central linkage, were prepared and their molecular structures were confirmed via mass spectrometric, IR and NMR spectroscopic techniques. The mesomorphic properties were identifed using differential scanning calorimetry, polarizing optical microscopy and X-ray diffraction analysis. All compounds showed enantiotropic mesomorphism. Whilst the lower members of the series, butyloxy, hexyloxy and octyloxy derivatives exhibited nematic phase, the medium members (decyloxy derivative) exhibited nematic and smectic A phases. The higher members (C12, C14, C16 and C18 derivatives) displayed smectic A phase only.

Schiff base derivatives of benzothiazoles were synthesized using substituted 2-aminobenzothiazoles and different substituted benzaldehydes. The structures of the synthesized Schiff bases were determined using Fourier transform infrared spectroscopy,
