Two‐Photon Cycloreversion Reaction of Diarylethene on Gold Nanotriangles

Abstract

Gold nanotriangles are employed for the two‐photon reaction of diarylethene in an enhanced electric field. When an infrared laser is irradiated onto colored diarylethene on a self‐assembled membrane of gold nanotriangles, decoloration is observed. The rate is dependent on the square of the intensity of light, which indicates that the decoloration is caused by a two‐photon reaction.
