제목 Single step self-organization of macroporous inverse opal nanocrystal superlattice films with1H,1H,2H,2H-perfluorooctyl-3-mercaptopropionate
초록 We describe here the single-step self-assembly of nanocrystal superlattice films infused with spatially ordered arrays of micrometer-size air holes by using a ligand 1H,1H,2H,2H-perfluorooctyl-3-mercaptopropionate(FOMA-SH). Evaporative cooling of an evaporating thin solvent film in a humid atmosphere leads to the formation of water droplets, or breath figures, that can be stabilized by nanocrystals coated with the appropriate ligands. The stabilized water droplets form very ordered arrays, which provide a temporary template that casts an ordered macroporous nanocrystal film. This process could serve as a reliable bottom-up self-assembly approach to the fabrication of two-dimensional waveguides with tunable optical properties for single-chip integration of photonic and electronic technologies.
