Single-molecule devices provide a reliable platform for exploration of the intrinsic properties of matters at the single-molecule level. The regulation of the electrical properties of single-molecule devices will be a key factor in enabling further advances in the development of molecular electronics. In this review article researchers in China introduce the optoelectronic effects that are involved in single-molecule devices, including photoisomerization switching, photoconductance, plasmon-induced excitation, photovoltaic effect, and electroluminescence. They summarize the optoelectronic mechanisms of single-molecule devices, with particular emphasis on the photoisomerization, photoexcitation, and photo-assisted tunneling processes. Discussion on the opportunities and challenges arising in the single-molecule optoelectronics field and propose further possible breakthroughs are also covered…read more.
