謝謝你大佬,我還有個問題就是我用2氨基對苯二甲酸98%(麥克林)和98%的ZrCl4(麥克林)合出來的并不是文獻(xiàn)中說的黃色,而是紅色的,這是我藥品的顏色嗎求指教 發(fā)自小木蟲Android客戶端 |

早就有文獻(xiàn)報(bào)道了 A new synthesis was developed for making large single crystals of UiO-66. It uses a combination of N,N-diethylformamide (DEF) and formic acid. A ratio of 1:1 by volume produces the largest crystals (Figure 2). The starting materials of ZrOCl2⋅8 H2O (0.037 mmol) and H2BDC (0.03 mmol) were dissolved in DEF prior to mixing and addition of formic acid. The resulting solution was placed in an oven for 2 days at 408 K. Furthermore, it was found that these conditions could be extended to a variety of zirconium salts and functionalized linkers. This includes ZrCl4, ZrBr4, Zr(OPr)4, H2BDC-Br, H2BDC-NH2, H2BDC-NO2, and H2BDC-Me2, thus demonstrating the versatility of these synthetic conditions (see the Supporting Information for further details). https://onlinelibrary.wiley.com/doi/10.1002/anie.201505461 |
