Modulating nanostructure morphology and mesomorphic properties using unsaturation in cardanol-azo benzenes.

Herein, we report the synthesis and self-assembly of a new class of amphiphilic azo dyes derived from a plant-based phenol, cardanol. Analysis of the self-assembly of these new azo derivatives was intriguing, and they exhibit some unique nanostructures, such as bicelles and microgel-like structures, and smectic-type thermotropic mesophases.
