早就有文献报道了

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).

谢谢你大佬,我还有个问题就是我用2氨基对苯二甲酸98%(麦克林)和98%的ZrCl4(麦克林)合出来的并不是文献中说的黄色,而是红色的,这是我药品的颜色吗求指教

请问,这个 oven 是指烘箱吗 不用反应釜也可行嘛
