Synthesis, mesomorphism and dielectric behaviour of novel basket shaped scaffolds constructed on lower rim azocalix[4]arenes

Abstract

A newly designed series of lower rim azocalix[4]arene basket type mesogens were synthesised and fully characterized. The proposed supramolecular organization displays needle shaped, rod like, focal conic and schlieren textures. These compounds were studied for their dielectric properties in the frequency range 100 Hz–2 MHz at variable temperatures (50–110 °C).
