Steric and electronic effects on mesophase stability of segmented liquid crystalline polymers with arylazomethine pendant groups

Abstract: The synthesis and thermotropic behavior are reported for a series of polyesters, 1, and its model compounds, 2, which bear a N-arylazomethine pendant group with para-substituents in order to evaluate electronic and steric effects on mesophase stability of segmented LCP with Y-shaped mesogens. Substituent effects on these polymer series and model compound series are dominated by steric effects. The results suggest that due to the conformational flexibility of the azomethine group this type of macromolecules can… Show more

“…Among the polymers with LC properties, in a few papers, the mesomorphic behaviour of polymers with azomethine bonds in the side chain were studied [48][49][50][51]. Sasaki et al [48] investigated the LC properties of polymers and copolymers with a methacrylate main chain, as shown in Fig.…”
