The strong absorption cross-section of plasmonic nanoparticles make them attractive candidates for light-activated chemistry, but much of the absorbed energy is transformed into heat to the surrounding medium. We propose that one way to overcome this problem is through nonradiative energy transfer to a photo-conductive polymer shell. At the same time, understanding the mechanisms that drive the energy-transfer efficiency are obscured by the innate heterogeneity of the nanoparticle/polymer interface. I will discuss our recent efforts to use single-nanoparticle scattering and fluorescence microscopy to quantify the energy transfer efficiency in gold/(poly)nickel(II) 2,9,16,23-tetra(amino) phthalocyanine hybrid nanomaterials.
