The recent discovery of lanthanide-based metal–organic frameworks (Ln-MOFs) offers the potential to extend the chemical sensing and catalysis capabilities of metal–organic frameworks (MOFs). Herein, a new europium functionalized material based on MIL-125(Ti)-NH₂ is synthesized by covalent postsynthetic modification and shows photocatalytic oxidation properties of α-phenethyl alcohol, and their fluorescence quenching behaviors are investigated. The catalytic efficiency is tested by monitoring the photocatalytic oxidation of α-phenethyl alcohol under ultraviolet light irradiation. Furthermore, MIL-125(Ti)-AM-Eu is developed as a fluorescence sensor integrated with its photocatalytic and luminescent properties. The MIL-125(Ti)-AM-Eu is used for detecting α-phenethyl alcohol, which could be successfully oxidized to acetophenone by the catalyst, and the fluorescence of MIL-125(Ti)-AM-Eu has changed accordingly.

后合成的MOF杂化体作为α-苯乙醇的非均相光催化剂和可重复使用的荧光传感器

基于镧系元素的金属有机骨架（Ln-MOF）的最新发现为扩展金属有机骨架（MOF）的化学传感和催化能力提供了潜力。本文中，基于MIL-125（Ti）-NH ₂的新型euro功能化材料通过共价后合成修饰合成α-苯乙醇，并显示出α-苯乙醇的光催化氧化性能，并研究了它们的荧光猝灭行为。通过监测紫外线照射下α-苯乙醇的光催化氧化来测试催化效率。此外，MIL-125（Ti）-AM-Eu被开发为集成了其光催化和发光特性的荧光传感器。MIL-125（Ti）-AM-Eu用于检测可被催化剂成功氧化为苯乙酮的α-苯乙醇，MIL-125（Ti）-AM-Eu的荧光也发生了变化。
