摘要：

Synthesis and characterization of new mesogenic N,N'-bis[3,4,5-tris(alkoxy)benzoyl]hydrazides are described. Polyhydrazides, containing the tris(alkoxy)benzoylhydrazide unit in the main chain have been prepared by polycondensation of a monoacylhydrazide and an acid chloride component. Three well defined model compounds with different substitution pattern of the aromatic core have been obtained. Phase transition temperatures and transition enthalpies of all compounds, determined by DSC-measurements, are given.
