AIE-active luminogen tetraphenylethene (TPE) was incorporated into a UiO-isoreticular zirconium metal-organic framework via the strategy of mixed dicarboxylate struts, and the resulting functionalized MOF shows a strong blue-green emission and selective sensing of nitroaromatic explosives 2,4,6-trinitrophenol (TNP) and 2,4-dinitrophenol (DNP) through fluorescence quenching. Moreover, the luminescent MOF exhibits efficient photocatalytic activity for aerobic cross-dehydrogenative coupling reactions mediated by visible light.
通过混合二羧酸支柱策略将具有聚集诱导发光特性的发光体四苯乙烯（TPE）引入UiO-异网状锆金属有机框架中，所得功能化金属有机框架呈现出强烈的蓝绿色发射，并通过荧光猝灭对硝基芳香族炸药2,4,6-三硝基苯酚（TNP）和2,4-二硝基苯酚（DNP）具有选择性传感。此外，该发光金属有机框架对可见光介导的需氧交叉脱氢偶联反应表现出高效的光催化活性。
