Experimental Section: All syntheses were carried out in air by mixing metal source(s) and capping ligand (e.g., thiols) in an organic solvent, such as benzene, toluene, or chloroform. An amine-borane complex was then added to the mixture and stirred until the reduction was complete. As an example, dodecanethiol-capped gold nanoparticles were prepared as follows: 0.25 mmol AuPPh3Cl was mixed with 0.125 mL of dodecanethiol in 20 mL of benzene to form a clear solution to which 2.5 mmol of tert-butylamine-borane complex was then added. The color of the mixture darkened gradually and became purple-red after stirring at 55 C for 5 min. TEM samples were prepared by dipping carbon-coated Cu TEM grids directly into the solution and drying in air for at least 2 h. As shown in Figure 1A, long-range close-packed superlattices of 6.2 nm gold nanoparticles (Figure 1A) can be obtained even without control over the evaporation rate |
