成功设计并通过水热法合成了一种具有功能性三维结构的镧系金属有机骨架Eu-4L，其配体为二苯胺四羧酸衍生物(H₄L)。Eu-4L的骨架中含有3D空腔，且其比表面积较高。Eu-4L不仅热稳定性较高，且在pH为3~11的范围内稳定性良好。Eu-4L可以作为荧光探针选择性识别稠环芳烃芘，其检测限为5 μmol·L^-1，具有较高的灵敏度，且具备可循环重复利用的特性。Eu-4L荧光识别芘的作用机理为稳态荧光识别机理。此外，对Eu-4L的荧光识别选择性、竞争能力也进行了详细地讨论。

By virtue of a 3∶1 complementary coordination strategy, a chiral heteroleptic metal-organic cage that contains divergent functional units, Pd-R(Zn), was precisely constructed via self-assembly of monodentate variational Znsalen ligands R^Zn and NADH (reduced nicotinamide adenine dinucleotide) mimic modified tridentate ligands with square-planar Pd ions. UV-Vis and luminescence spectra experiments reveal that different anions could selectively interact with different sites of Zn-salen modified metal-organic cages to achieve the structural regulation of cage compound, by using the differentiated host-guest electrostatic interactions of counter ions with metal-organic hosts. Compared to other anions, the presence of chloride ions caused the most significant fluorescence emission enhancement of Pd-R(Zn), meanwhile, the UV-Vis absorption band attributed to the salen aromatic backbone showed an absorption decrease, and the metal-to-ligand induced peak displayed a blue shift effect. Circular dichroism and ¹H NMR spectra further demonstrate that the introduction of chloride anions is beneficial to keeping a more rigid scaffold.
