The surface plasmons produced by the collective oscillation of conduction electrons in metal nanostructures can redistribute not only the electromagnetic field spatiotemporally, but also the excited carriers. Various effects caused by surface plasmons, including enhanced electromagnetic fields, local heating, excited electrons and excited holes, can drive chemical reactions. In this work, the regularly-arranged Au nanoarray catalytic substrate is prepared based on an anodic aluminum oxide template. When the excitation light of a specific wavelength irradiates on the substrate, a large number of regularly-arranged local surface plasmon enhancement regions will be generated on its surface. By taking advantage of surface enhanced Raman spectroscopy, the 4,4′-dimercaptoazobenzene is synthesized by the photocatalytic reaction of p-aminothiophenol as a probe driven by local surface plasmon. After that, the sodium borohydride is introduced in situ. Under the same experimental conditions, the product 4,4′-dimercaptoazobenzene is driven by plasma to produce p-aminothiophenol again. This research work will achieve the drawing and erasing of molecular graphics on a micro scale and a nano scale, as well as information encryption, reading and erasing, which has a strong application value.
