Abstract

Azobenzene containing polymers have been shown to have a large potential for high capacity olographic information storage. However, it has been difficult to fabricate thick films of the polymers with good op~ical quality so far. Liquid crystalline block copolymers prepared by Atom Transfer Radical Polymerization and based on azobenzene methacrylate and methyl methacrylate show some promise due to the observed block segregation. Thus, lamellar nanostructure was observed'when the azobenzene content was > 20% by weight, and both birefringence and dichroism can be induced by linearly polarized 488 nm light. The formation of azo-aggregation inside the azo blocks is strongly,reduced when going from the homopolymer to the copolymers.
