Photo-induced chemical reaction of p-aminobenzenthiol (ABT) was investigated using the lithographically fabricated mechanically controllable break junction (MCBJ). The ABT single-molecule junction was formed at the nanogap of the MCBJ and the formation was confirmed by the electronic transport measurement including current versus bias voltage characteristics. Light irradiation at the nanogap revealed that ABT molecules were subject to photo-induced dimerization, which was confirmed by measuring SERS spectrum. In addition, we tuned the gap size using MCBJ technique and demonstrated that the photo-induced dimerization was absent for the molecules at the wide gap.
