Synthesis and Characterization of Azobenzene Chromophore Containing Polymeric Nanospheres

Abstract

Abstract: A new strategy based on electrostatic interaction technology was provided for design of novel side chain azobenzene complex(P4VP-r-AN/MY) from the protonated P4VP-r-AN(P4VP+-r-AN) and azobenzene dye metanil yellow(MY) in aqueous solution. The self-assembly behavior and morphologies of P4VP-r-AN/MY were investigated by means of FTIR, DSC, UV-Vis, TEM and HRTEM-EDS. The possible formation and transformation progresses of P4VP-r-AN/MY aggregations were also preliminary discussed in this paper. The azobenzene complex was subjected to solvent-induced self-assembly in THF/water mix solvent to construct avariety of morphologies. The azobenzene complex P4VP-r-AN/MY could be self-assembled and aggregated in aqueous solution, and the aggregations shown to be solid polymeric nanospheres on the sizes of 10—250 nm in diameters. The spherical ordered structures of P4VP-r-AN/MY were destroyed in DMF solvent, and converted into film structure. However, in DMF/H2O mixed solvent with a H2O mass fraction of 62.5%, azobenzene chromophore containing polymeric hollow nanospheres on the sizes of 30—200 nm in diameters were directly observed by TEM. The results indicate that the composition of solvents(the mass ratio of H2O and DMF) plays an important role in controlling the shape of self-assembly morphologies.
