      abstract     = {Molecular electronics aims at gaining control over the
                      operation of macroscopic devicesby employing molecules as
                      building blocks. To fulfill the spectrum of functions,
                      varioustypes of molecules are designed including
                      photochromic molecules. Diarylethenes are anexample of the
                      latter one and are discussed as potential optoelectronic
                      switches, which canreversibly transition between two forms
                      with different electrical conductance and opticalabsorbance.
                      By exposure to UV light, the overall electronic structure
                      alters from nonconjugation(open) to end-to-end conjugation
                      (closed) forms, while visible light reversesthe
                      process.These features enable to intensively employ
                      diarylethenes in a single-molecule junctionupscaling their
                      usage to large-area ensemble contacts. However, in general,
                      the transitionbetween closed and open states (opening)
                      exhibits a lower quantum yield compared tothe reverse
                      UV-activated process of closing. These unequal switching
                      rates can be problematicfor optoelectronic molecular
                      contacts relying on reversible switching. Thereby, inthis
                      work, the novel strategy is proposed to use surface
                      plasmon-enhanced electromagneticfields to accelerate the
                      visible-light-mediated cycloreversion reaction. To
                      implementthis concept into large-area molecular contacts
                      with vertical geometry, a plasmonic fieldenhancement of gold
                      films perforated with nanoholes was employed.The surface
                      plasmon resonance properties of nanohole arrays fabricated
                      by nanospherelithography are systematically studied as a
                      function of the geometrical features such aslattice
                      constant, thickness, and hole diameter. Moreover, nanohole
                      arrays are testedin different media, e.g. aqueous solution,
                      revealing a novel phenomenon of enhancedtransmission in the
                      visible range, which can be applied not only for enhancing
                      visible-lighttriggeredchemical reactions but for other
                      applications like biosensing, live-cell imaging,etc.},
