The NMR tube was closed with a septum and equipped with an air balloon (approximate 500 mL) containing approximately 100 mL of O2 (4.5 mmol, 112 equiv.) and approximately 12.6 mL of H2O (gas, 0.56 mmol, 14 equiv., air relative humidity = 75%). The solution (not agitated) was placed at room temperature and was monitored by 1H NMR. 100 C was used for the decomposition of 1h, and 150 C was used for the decomposition of 1i and 1j. The precipitate in the NMR tube was removed by quick filtration using a membrane filter before each 1H NMR measurement. The ratio of Cu-NHC, urea, and imidazolium were calculated through the integration of 1H NMR, using the normalization method.

A mixture of 1.05 g (4 mmol) Cu(AcAc)2, 0.44 g (2 mmol) Zn(OAc)2, 0.38 g (2 mmol) SnCl2, and 20 ml OLA were added into a 100 ml three-neck round-bottom reaction flask connected to a nitrogen gas cylinder. The mixture solution was always stirred vigorously in the flask purged with high pure N2 gas (99.999%), during the whole synthesis. After heated at 130 C for 30 min, the mixture solution became brownish. The brownish solution was injected with 8 ml of sulfur – OLA solution (1 M), then heated at the reaction temperature T reaction 240-280 C for 1 h. When its color changed from dark brownish into blackish, the mixture solution (or product) was cooled down to room temperature (RT) and added with 15 ml of toluene for dispersing by sonication. To washing or purifying the product, 40 ml of ethanol was firstly added to let the nanoparticles flocculate and precipitate; then precipitates of nanoparticles were collected by centrifuging at 4000 rpm for 20 min and the supernatant liquid was removed; the collected precipitates were dispersed in toluene again by sonication; then ethanol was added for precipitates, new precipitates were collected again by centrifuging. The above process was repeated for three times. The final precipitates (or CZTS nanoparticles) were divided into two parts: (1) CZTS nanoparticles dispersed in toluene to form a stable ink solution and (2) CZTS power dried in a vacuum oven.
