In this work, we report the synthesis of AB₂ shaped amphiphilic azo block copolymer by macromolecular azo coupling reaction. The product and intermediates were characterized by various methods. The selfassembly in selected solvents and photo-responsive behavior of the copolymer were studied bymeans of UV-vis spectrophotometry and TEM. Spherical aggregates can be obtained by gradually adding water into the solution of this amphiphilic azo block copolymer. Upon irradiation with polarized UV (365 nm) light, the aggregates can be elongated in the polarized direction.
