A novel hydrazide-based mesogenic (nematic) Schiff-base, N-(4″-pyridylcarboxamido)-4-(4′-hexyloxybenzoato)salicylaldimine, Hpychbsal (abbreviated as H 2 L) was prepared and its structure studied by elemental analyses, mass, NMR and IR spectra and single crystal XRD (triclinic space group P1¯ with Z=4) techniques. The Schiff-base behaves as a uninegative bi/tridentate species in its non-mesogenic...
A novel Schiff-base, N,N′-di-(4′-pentyloxybenzoate)salicylidene-1,8-diamino-3,6-dioxaoctane (H 2 L 4 ) with the mesogenic phase, nematic droplets, was prepared and its structure studied by elemental analyses and mass, NMR and IR spectra. The di-negative tetra-dentate bonding of the Schiff-base in the non-mesogenic complex, [ZnL 4 ], as implied on the basis of IR and NMR spectral...
