TL;DR: The mesomorphic properties of newly synthesized homologous series of calamitic liquid crystals containing ester and Schiff base groups as linker and Raman marker bands of phenyl rings, Schiff base and ester groups confirm the phase transitions.

TL;DR: In this article, a liquid crystal based sensor was developed to detect hydrazine vapour using cross-polarizing optical microscopy under crossed polarizers, which was shown to have a dark to bright optical texture upon exposure of hydrazines vapours.

TL;DR: In this article, the synthesis, characterization and investigation of a new liquid crystalline series of ester containing aroylhydrazones with a lateral hydroxyl group, N-[4-(4′-alkoxy)benzoyloxy-2-hydroxy-benzylidene]-N′-[4″-alkoxine]-hydrazine (C m, n LH), with the same or different peripheral alkoxy chains, and some of their nickel (II) and copper(II) complexes are described.
