Effects of Photochromic Furan-Based Diarylethenes on Gold Nanoparticles Aggregation

Abstract The photochromic properties of furan-based diarylethenes and their interaction with citrate-capped gold nanoparticles were investigated by ultraviolet/visible absorption spectroscopy and transmission electron microscopy. We identified the optimal concentration of diarylethenes in water-ethanol mixture required for stability of colloidal systems. Nanoparticles coupled with diarylethene derivatives exhibit a new surface plasmon resonance band coming from their aggregation. We analyzed the effects of functional side-chain groups on aggregation process. These results can be considered as a basis for further designing of novel hybrid nanomaterials and optoelectronic elements

The color changes that represents the interection of DAEs with AuNPs: (a) C5F-MTSC and (b) C5F-TSC. The volume ratio water to ethanol is equal to 4:1, C DAE = 1 × 10−6, 5 × 10−6, 1 × 10−5 mol·L−1. The concentration of gold C Au = 2 × 10−4 mol·L−1 was constant for all series. The spectra of the corresponding solutions are presented in Fig. 3. (PPT 128 kb
