99% 4-Aminobenzoic acid 4-aminophenyl ester 20610-77-9 Usage

4-aminophenyl-4′-aminobenzoate (APAB) is off-white to white powder. Liquid crystalline polymers (LCPs) were synthesised using pyromellitic dianhydride and 4-[(4-aminobenzylidene)amino]aniline or 4-aminophenyl-4-aminobenzoate.

Liquid crystalline thermosets (LCT) from diaromatic mesogenic diepoxides and aromatic diamines: synthesis and phase behaviour of model compounds and intermediate structures

Werner Mormann, Markus Bröcher

Polymer Volume 39, Issue 25, December 1998, Pages 6597-6603

The study of the reaction of 4-(2,3-epoxypropoxy)-4′-ethoxy-biphenyl (1) and of 4-butoxyphenyl-4-(2,3-epoxypropoxy)-benzoate (2) with 4,4′-diaminobiphenyl (3), and 4-aminophenyl-4-aminobenzoate (4) has shown that model compounds are very useful for the understanding and for modelling of the formation of a liquid crystal thermoset.

Synthesis of dinuclear complexes of rhenium(I) as potential metallomesogens

Guillevic, Marie-Andree,Light, Mark E.,Coles, Simon J.,Gelbrich, Thomas,Hursthouse, Michael B.,Bruce, Duncan W.

, p. 1437 - 1445 (2007/10/03)

Seven anisotropic diimines and their corresponding dinuclear complexes of rhenium(i) have been synthesized. In common with related inline ligands which have been synthesized previously, the new diimines were mesomorphic showing smectic C and nematic phases and, in some cases, smectic I and crystal J phases. However, none of the orthometallated, dinuclear complexes showed any liquid crystal phases. The Royal Society of Chemistry 2000.
