- Other significant methods are by aryldiazonium salt azo group formation with compounds that contain reactive electron lone pair donating centers like 3 pyridine, β dicarbonyl.
- Another family of liquid crystalline polyamides which can have its polar amide side chain or a main azo group chain also demonstrates significant nematic smectic thermal stabilization effects.
