Synthesis and Characterization of Poly(Propyleneimine) Dendritic Azo Compound

The first generation of poly(propyleneimine) dendrimer is synthesized by improving reaction conditions, and then the poly(propyleneimine) dendritic architecture with azo groups is prepared by modifying with N acetylsulfanilyl chloride. This compound may be applied as holography materials in view of its peculiar optical properties. The products are proved to be in accord with theoretical structure by characterization of infrared spectrum, element analysis and nuclear magnetic resonance.
