Before each experiment, the [1,3-(pr)2im]Br was dried at 75 C under reduced pressure. The PAs were prepared by the following general procedure: as an example for the preparation of PA10aI, 0.10 g (1.70 9 10-4 mol) of diacid 8, 0.0338 g (1.70 9 10-4 mol) of diamine 9a and 0.25 g of [1,3-(pr)2im]Br were placed in a porcelain dish and the mixture was ground completely for 5 min, then 0.11 mL (4.26 9 10-4 mol) of TPP was added, and the mixture was ground for 3 min. The reaction mixture was irradiated in the microwave oven for a period of 40 ? 40 ? 20 s at 70% of power level. The resulting viscous solution was poured into 30 mL of methanol, filtered, and dried under vacuum to give 0.118 g (88%) of PA10aI. |

每次實驗前均對[1,3-(pr)2im]Br進行減壓干燥。 PAs是通過以下方式制備的:以制備PA10aI, 0.10 g (1.70 9 10-4 mol) of diacid 8為例,首先將0.0338克二元胺和0.25克[1,3-(pr)2im]Br共同放置于磁碟中,并混合研磨5分鐘。然后加入0.11毫升的(4.26 9 10-4 摩爾)的TPP,再繼續(xù)研磨3分鐘。再將混合物放在微波爐中在70%強度下輻照40 ? 40 ? 20 s。最后, 將獲得的粘稠液體倒入30毫升的甲醇中過濾,然后在真空環(huán)境中干燥,即可獲得0.118克的PA10aI。 |

每項實驗開始前,[1,3-(pr)2im]溴都在低壓,75攝氏度的條件下烘干。 同時,通過以下通用的程序提前制備好對氨基水楊酸:作為制備PA10aI的例子,首先在蒸發(fā)皿中放入0.10 g的二酸8(1.70 9 10-4 mol),0.0338 g的二元胺(1.70 9 10-4 mol),以及0.25 g溴[1,3-(pr)2im]進行混合,將混合物充分研磨5分鐘,然后加入0.11毫升的磷酸三苯酯(4.26 9 10-4 mol),在詞研磨3分鐘。然后將已經(jīng)發(fā)生反應的混合物放入微波爐,以70%的微波功率對其進行輻射,時長控制在40 ? 40 ? 20 s。 將產(chǎn)生的粘性溶液導入30ml的甲醇,然后進行過濾,在真空條件下進行烘干,可以產(chǎn)出0.118g濃度為88%的PA10aI。 |
