| Outline of Final Research Achievements |
We synthesized several diarylethene polymers having absorption maximum of the closed-ring isomer around the LSPR band, and fabricated Ag nanoparticles covered with their polymers. We quantitatively evaluated the difference in the photocycloreversion reaction of the nanoparticles by various wavelength of the incident light. We synthesized gold nanoparticle network consisting of gold nanoparticles and diarylethene polymers (Au-poly(DE)-NW). Au-poly(DE)-NW was evaluated by dynamic light scattering and transmission electron microscopy. Au-poly(DE)-NW obtained is soluble in an organic solvent, and the localized surface plasmon resonance of the network was shifted to longer wavelength than that of the single gold nanoparticle. The network showed photochromism in an organic solvent. The photocycloreversion reaction of the diarylethene moiety was found to be promoted in the gap mode of the gold nanoparticles.
