Fifteen azomethineimines derived from C-aminopyrazoles and aromatic aldehydes have been prepared and fully characterized (IR, MS, 1H and 13C NMR in solution and 13C CPMAS NMR). The benzaldehyde bearing at position 4 n-decyloxy or a n-butyloxycarbonylethyloxy substituents and at position 2 a hydrogen or a hydroxy substituent have been tested for mesogenic properties. Only 5 [1H-4-(4-n-decyloxy-2-hydroxybenzylideneaminopyrazole)] presents a mesogenic behaviour (smectic A) on cooling.
