通过使用高通量的方法，FeCl（3）和2-氨基对苯二甲酸在质子和非质子反应介质中的溶剂热反应进行了系统的研究。因此，MIL-53，MIL-88和MIL-101的等网格结构的形成领域的Fe（III）和氨基对苯二甲酸酯的基础上，可以确定为第一次。所得的具有氨基官能化孔的3D框架材料已经使用X射线衍射、IR光谱和热重、元素和能量色散X射线分析来表征。由于所应用的高通量方法，在短时间内获得了高密度的信息，这使得能够提取重要的反应趋势，并有助于更好地理解组成以及工艺参数在无机-有机杂化材料合成中的作用。我们已经发现，反应介质的性质对结构形成具有最深远的影响。此外，起始混合物的浓度（即，溶剂含量）和温度也被认为是形成不同混合相的关键参数。
Through the use of high-throughput methods, solvothermal reactions of FeCl(3) and 2-aminoterephthalic acid in protic as well as aprotic reaction media were systematically studied. Thus, the fields of formation of the isoreticular structures of MIL-53, MIL-88, and MIL-101 based on Fe(III) and aminoterephthalate could be identified for the first time. The resulting 3D framework materials with amino-functionalized pores have been characterized using X-ray diffraction; IR spectroscopy; and thermogravimetric, elemental, and energy dispersive X-ray analysis. Due to the applied high-throughput method, a high density of information was obtained in a short period of time, which allows the extraction of important reaction trends and contributes to a better understanding of the role of compositional as well as process parameters in the synthesis of inorganic-organic hybrid materials. We have found that the nature of the reaction medium has the most profound impact on structure formation. Furthermore, the concentration of the starting mixture (i.e., the solvent content) and the temperature have also been identified as key parameters for the formation of the different hybrid phases.
