    • 2 (99.99+%), 0.13 g of S (99.98%) were added to 40 mL of OLA (70%) in a 100 mL three-neck flask on a Schlenk line. The reaction mixture was degassed under vacuum for 2 h, purged with N2 for 30 min at 110°C, heated to 280°C for 1 h, and then cooled to room temperature. The nanocrystals were then isolated by precipitation with ethanol followed by centrifugation. Solid reaction byproducts and poorly capped nanocrystals were removed by redispersion in chloroform and centrifugation at 8000 rpm for 2 min. The nanocrystals were washed three more times by solvent/antisolvent precipitation with chloroform/ethanol. A typical reaction yielded ∼200 mg of nanocrystals.
