Recently, the concept of “effective utilization of photons” has attracted attention in photochemistry for an increase in excitation probability. Here, we focus on metallic nanostructures showing near-field enhancement effects induced by localized surface plasmon resonance, which act as photochemical reaction fields. We have verified the two-photon photopolymerization of negative photoresists on the closely spaced gold nanoparticles irradiated by a weak incoherent light source. We also demonstrated an efficient plasmonic photoelectric conversion by visible to near-infrared light using electrodes, in which gold nanoblocks were elaborately arrayed on the surface of a TiO2 single crystal.
