Abstract
Herein, we report a de novo synthesis approach to produce bandgap-controlled polyaniline (PAni) nanostructure via Mn-mediated oxidative polymerization at the catalytic nanoreactor. To achieve systemic nanoconfined polymerization, manganese oxide (MnOx) nanoparticles coated with silica were used as the sacrificial nanotemplate. Interestingly, the catalytic nanoreactor simultaneously allowed the nanoconfined oxidative polymerization and controlling of the bandgap. MnOx could be reduced by the addition of aniline monomers and consecutive redox reaction at the nanoreactor. Furthermore, core cavity was generated, and ionized Mn could control the bandgap by coordination at the nanostructures.
