Photoswitchable Hybrid Nanosystems Based on Diarylethene Molecules and Gold Nanoparticles
In this chapter, hybrid nanomaterials based on diarylethene molecules and gold nanoparticles (GNPs) are described. The interest of diarylethene derivatives incorporated in nanosystems and coupled to GNPs is first introduced. Different strategies to prepare hybrid nanosystems are then described, pointing out designs presenting specific merits and flaws. The photochromism-plasmonic coupling is presented, considering both units of the hybrid nanosystem. On the one hand, the photochromic reaction of the diarylethene molecules greatly modifies the surface plasmon resonance (SPR) mainly due to a change of the local refractive index. On the other hand, the enhanced electromagnetic field at the surface of the GNPs induces an enhancement of the photochromic kinetics under visible light irradiation. These cross talk interactions are also considered with the help of theoretical methods, providing new tools to investigate the molecular-plasmonic coupling. Such experimental and theoretical advances are very promising in the field of innovative and multifunctional hybrid nanomaterials.
