Abstract
into the organic phase for controlled reduction of selenolate-Au(i) complexes in organic phase. Using this strategy, size tuning of Au NCs at the atomic level could be achieved by simply varying the amount of TOAB. The high yields of Au NCs (≥76%) together with the short synthetic time (≤3 h) and size-tuning capability further illustrate the attractiveness of this synthetic strategy. These advantages also present the classical B-S method with greater strength and flexibility towards NC synthesis.
