mof和zif的合成通常伴随着不需要的副产物的形成。在N，N-二乙基甲酰胺（DEF）中合成ZIF-11也有相杂质的报道。在本系统的研究中，反应混合物中的水残可以确定为在ZIF-11合成中形成相杂质ZIF-7-III的主要原因之一。引入了“结晶度”和“相指数”参数来量化相变。
The syntheses of MOFs and ZIFs are often accompanied by the formation of unwanted byproducts. Also for the ZIF-11 synthesis in N,N-Diethylformamide (DEF), phase impurities have been reported. In this systematic study, water residues in the reaction mixture could be identified as one major reason for the formation of the phase impurity ZIF-7-III within the ZIF-11 synthesis. The parameters ‘crystallinity’ and ‘phase index’ were introduced to quantify the phase transition.
