Facile Synthesis of Gold Nanoparticles Using Aggregates of Pentacenequinone Derivative and their Catalytic Activity for Oxidative Polymerization, Homocoupling and Reduction

The fluorescent aggregates of pentacenequinone derivative 3 serve as reactors for the preparation of gold nanoparticles through irreversible oxidative polymerization to furnish pentacenequinone based mesoporous polyaniline derivative. Further, gold nanoparticles so generated also exhibit excellent catalytic activity for conversion of phenyl boronic acid to biphenyl and reduction of nitro aromatics to amino derivatives.
