Shape-limitation of plasmonic cores is understandable due to the possible aggregation of bigger and anisotropic nanostructures in the presence of Azo, especially in organic solvents. Nonetheless, by using small, isotropic nanoparticles exhibiting limited light-harvesting properties, studies were restricted to the exclusive investigation of Azo's dark (thermal) Z-E isomerization. Both intraband transitions and Localized Surface Plasmon Resonance (LSPR) bands of spherical AuNPs are in tooclose proximity to the absorption maxima of the π→π * and n→π * transitions of Azo compounds. As a result, plasmon contributions cannot be properly isolated, and the investigation of the light-driven isomerization of such binary systems is complicated. Hence, the knowledge about plasmon-assisted isomerization of Azo is very scarce. Yet, plasmonic nanostructures are a source of powerful lightinduced catalytic tools such as heat, electric field enhancement, and hot (i.e. highly energetic) carriers. It can be hypothesized that these phenomena could be potentially used to indirectly control Azo isomerization, both E-Z and Z-E reactions, affecting their mechanisms and kinetics.
