Linear and four-arm star polystyrene samples prepared by RAFT polymerization were grafted to gold surfaces directly via their thiocarbonylthio-end groups. Nanoscale polymer patterns were subsequently formed via constrained dewetting. The patterned polymer films then served as a template for the precise arrangement of gold nanoparticles in a monolayer with a well-defined and regular structure. Using star polymers as a linker between the planar gold surface and the particles, the structural stability of the arranged particles can be further enhanced. The surface-bound nanocomposite films made of polymer and nanoparticles can also reversibly switch their nanostructures by simple wetting or dewetting treatment.

Raft Agent

A cholesterol-functional trithiocarbonate reversible addition–fragmentation chain transfer (RAFT) agent was synthesized and employed to generate well-defined poly(polyethylene glycol) acrylate with cholesterol chain termini using RAFT polymerization. Subsequently, the polymers were grafted onto the surface of gold nanoparticles using the trithiocarbonate functionality to bind to the gold surface. The cholesterol moieties were then modified via complexation with β-cyclodextrin. The step-by-step modification of gold nanoparticles was characterized by dynamic light scattering, attenuated total reflection infrared spectroscopy and surface plasmon resonance analysis.
