合成的量子點(diǎn)不加堿調(diào)ph可以嗎 已有1人參與
|
|
最近合成CdS的量子點(diǎn),加不同巰基小分子修飾(巰基乙酸),不加堿調(diào)節(jié)ph這一環(huán)節(jié),合成出來可以嗎。我合成出來的東西不溶于甲醇,也不溶于水,只是在dmf中溶解,這個(gè)對嗎。附上參考文獻(xiàn):11-Mercaptoundecanoic acid (MUA) in DMF (0.15 mol/L,40 mL) was added to an aqueous solution of cadmium chloride (CdCl 2Æ 2.5H2O, 3 mmol, 2 mL) and stirred for 15 min.Aqueous sodium sulfide (Na2 S, 1.6 mmol, 2 mL) was addeddropwise to the solution, which was then stirred for 4 h atroom temperature in the dark. The yellow reaction mixturewas slowly dehydrated by distillation under reduced pressurewhile adding fresh DMF to maintain the concentration of CdSNPs in suspension. NaCl was removed by centrifugation three times, yielding carboxyl-anchored CdS NPs in DMF CARBON 48 (2010) 1177– 1185 |
