Abstract: We investigate the presence of $(trans-10b,10c-dimethyl-10b,10c-dihydropropane)$ (DHP) photochromic molecular switches on 2D gold nanoparticle networks after molecular place exchange. We study the networks using spectoscopy, as the presence of the molecular switches on the network changes the surface plasmon resonance absorption frequency. We observed a redshift of $20\ nm$ and an additional peak broadening of $2\ nm$ (FWHM) of the absorption peak of the network compared to before molecular place exchange. From this we conclude that the molecules are present on the network after molecular place exchange.
