Azo liquid crystal polymers are promising materials for optical information storage, optical switching and nonlinear optical equipment because of their photoisomerization and photochromic. So they have received much attention at home and abroad in recent years. This paper briefly outlines the structure of azo liquid crystal polymer, focuses on the current research situation of the main-chain azo liquid crystal polymers, side-chain azo liquid crystal polymer, dendritic azo liquid crystal polymer, star azo liquid crystal polymer and the application progress in optical storage, optical switching and optical modulation polarizer, and points out the prob- lems and research directions.
