Synthesis, mesomorphism and dielectric behaviour of basket shaped scaffolds

21 Feb 2013

Shobhana Menon and colleagues from Gujarat University, India, have designed a new series of lower rim azocalix[4]arene basket-type mesogens. Along with their rigid core, calix[4]arenes are easy to functionalize with various linkages and flexible aliphatic chains at the hydrophilic hydroxyl groups. They are therefore promising candidates for liquid crystal applications.

The new basket-shaped scaffolds were fully characterised, and the proposed supramolecular organisation displays needle shaped, focal conic, rod like and schlieren textures (see image).
