Photoisomerisation and ligand-controlled reversible aggregation of azobenzene-functionalised gold nanoparticles.

چکیده
The photochemical behaviour of functionalised gold nanoparticles (AuNPs) carrying azobenzenethiolate-alkylthiolate monolayers was investigated. Repeated trans-cis and cis-trans isomerisation cycles could be performed in all cases with high efficiency. Reversible photoinduced aggregation was observed when azothiolates with long alkyl spacers (≥C7) were combined with short (C5) alkylthiolate coligands. The choice of a coligand thus offers control over the aggregation properties of the nanoparticles.

Optical switching of coupled plasmons of Ag-nanoparticles by photoisomerisation of an azobenzene ligand.
The optical switching of coupled plasmons of silver nanoparticles derivatised with a photoisomerisable azobenzene ligand is presented. It is shown that nanoparticle clusters, linked with an azobenzene dithiol molecule, display switchable optical properties. The photoisomerisation of the linker molecule was used to vary the separation between nanoparticles, which was monitored by changes in the ...
متن کاملUsing polymers to photoswitch the aggregation state of gold nanoparticles in aqueous solution.
Gold nanoparticles (AuNPs) coated with a water-soluble polymer displaying a photoswitchable lower critical solution temperature (LCST) were synthesized, and the photoinduced change in the aggregation state of AuNPs was investigated. The photoactivity of AuNPs was conferred by tethering on the surface a random copolymer of N,N-dimethylacrylamide and N-4-phenylazophenyl acrylamide (P(DMA-co-Azo))...
متن کاملReversible Phase Transfer of Nanoparticles Based on Photoswitchable Host–Guest Chemistry
An azobenzene-containing surfactant was synthesized for the phase transfer of α-cyclodextrin (α-CD)-capped gold nanoparticles between water and toluene phases by host-guest chemistry. With the use of the photoisomerization of azobenzene, the reversible phase transfer of gold nanoparticles was realized by irradiation with UV and visible light. Furthermore, the phase transfer scheme was applied f...
متن کاملTunable, Controlled and Reversible Assemblies of poly(ethylene oxide-st-propylene oxide) grafted Gold Nanoparticles
In recent years, assemblies of functionalised gold nanoparticles (AuNPs) have received a growing interest as a route toward hybrid materials with new functionalities. Here, we report on thermally reversible assemblies formed by mixing thermosensitive polymerprotected AuNPs and Pluronic triblock copolymers. Amino-terminated copolymers, poly(EO-st-PO), with different EO/PO ratios were coupled by ...
متن کاملGold nanoparticles used as a carrier enhance production of anti-hapten IgG in rabbit: a study with azobenzene-dye as a hapten presented on the entire surface of gold nanoparticles.
The azobenzene moiety, well-known not only for its reversible cis-to-trans photoisomerization but also as a hapten, does not induce antibodies on its own, but it reacts with antibodies raised against conjugates with protein carriers. Hence we selected azobenzene dye as an indicator to assess the possibility of having gold nano-particles act as an immunological carrier instead of protein carrier...
