A novel set of four functionalized hydrophobic UiO-66-NHR series were synthesized through postsynthetic procedures, utilizing various benzoyl chlorides and UiO-66-NH as starting materials. This synthesis method was carried out by employing p- (1) and o-toluoyl (2), as well as 2- (3) and 4-fluorobenzoyl (4) substituents. The analysis of the resulting compounds was performed using conventional spectroscopic methods such as FT-IR and H NMR to quantify the conversion rate into amide. Furthermore, SEM and XPS techniques were employed for morphological and surface analysis. Finally, the evaluation of the chemical stability and contact angle using the sessile drop method was performed to evaluate the technological potential of these compounds for application in aqueous and acidic media (such as selective separation of different metals and wastewater recovery).
通过后合成程序，利用各种苯甲酰氯和 UiO-66-NH 作为起始原料，合成了一组新型的四种功能化疏水 UiO-66-NHR 系列。该合成方法是通过使用对（1）和邻（2）以及 2-（3）和 4-氟苯甲酰（4）取代基来实现的。使用常规光谱方法（如 FT-IR 和 H NMR）对所得化合物进行分析，以定量酰胺的转化率。此外，还使用 SEM 和 XPS 技术进行形态和表面分析。最后，使用固着液滴法评估化学稳定性和接触角，以评估这些化合物在水相和酸性介质（如不同金属的选择性分离和废水回收）中的应用技术潜力。
