Herein we systematically investigated the coordination assembly behavior of ZrL cages with Eu ions at room temperature. Through adjustment of the concentration of Eu salt and changes of the type and molar ratio of the solvent, a series of ZrL-Eu structures with different structure dimensionalities have been synthesized and structurally characterized. In addition, we also studied the optical properties of these materials in detail, including the fluorescent and third-order nonlinear-optical properties. Most notably, a 2D layer structure with a strong aromatic π···π-stacking force exhibits a good optical-limiting effect.
在此，我们系统地研究了室温下ZrL笼与铕离子的配位组装行为。通过调整铕盐浓度以及溶剂类型和摩尔比的变化，合成并对一系列具有不同结构维度的ZrL-Eu结构进行了结构表征。此外，我们还详细研究了这些材料的光学性质，包括荧光和三阶非线性光学性质。最值得注意的是，具有强芳香π···π堆积力的二维层状结构表现出良好的光限幅效应。
