Benefiting from the development of molecular electronics and molecular plasmonics,the interplay of light and electronic transport in molecular junctions has attracted growing interest among researchers in both fields,leading to a new research direction of“single-molecule optoelectronics”.Here,we review the latest developments of photo-modulated charge transport,electroluminescence and Raman spectroscopy from single-molecule junctions,and suggest future directions for single-molecule optoelectronics.
