      abstract     = {Diarylethene molecules are discussed as possible optical
                      switches, which can reversibly transition between completely
                      conjugated (closed) and nonconjugated (open) forms with
                      different electrical conductance and optical absorbance, by
                      exposure to UV and visible light. However, in general the
                      opening reaction exhibits much lower quantum yield than the
                      closing process, hindering their usage in optoelectronic
                      devices. To enhance the opening process, which is supported
                      by visible light, we employ the plasmonic field enhancement
                      of gold films perforated with nanoholes. We show that gold
                      nanohole arrays reveal strong optical transmission in the
                      visible range $(∼60\%)$ and pronounced enhancement of
                      field intensities, resulting in around $50\%$ faster
                      switching kinetics of the molecular species in comparison
                      with quartz substrates. The experimental UV–vis
                      measurements are verified with finite-difference time-domain
                      simulation that confirm the obtained results. Thus, we
                      propose gold nanohole arrays as transparent and conductive
                      plasmonic material that accelerates visible-light-triggered
                      chemical reactions including molecular switching.},
