Highly luminous lanthanide metal–organic gels (Ln-MOGs) can act as fluorescent probes for the detection of organic amines and can also be used to build white-light emitting materials based on the different luminescent properties of lanthanide ions. Here, we reported a Ln-MOG constructed with a 3,5-di(2′,4′-dicarboxylphenyl)benozoic acid (DPBA) ligand and Tb³⁺. Tb-MOG has an excellent fluorescence detection effect on organic amines including ethylenediamine, triethylamine, diisopropylamine and aniline in aqueous solution, and their detection limits reach a sub-ppm level. Considering the practicality, a Tb-MOG testing paper was prepared by a spin coating process, which can detect volatile organic amine vapors with good recyclability. Additionally, a single-phase white-light Tb_0.84Eu_0.16-MOG material was realized by in situ doping of Tb-MOG with Eu³⁺ and reasonably utilizing the blue emission of DPBA.

耐水的镧系金属有机凝胶，用于检测有机胺和发白光

高发光镧系金属有机凝胶（Ln-MOGs）可以用作检测有机胺的荧光探针，还可以根据镧系元素离子的不同发光特性用于构建发射白光的材料。在这里，我们报道了由3,5-二（2'，4'-二羧基苯基）苯甲酸（DPBA）配体和Tb ³⁺构成的Ln-MOG 。Tb-MOG对水溶液中的乙二胺，三乙胺，二异丙胺和苯胺等有机胺具有出色的荧光检测效果，其检出限达到亚ppm级。考虑到实用性，通过旋涂工艺制备了Tb-MOG试纸，该试纸可以检测挥发性有机胺蒸气，并且具有良好的可回收性。另外，单相白光Tb _0.84 Eu通过用Eu³⁺原位掺杂Tb-MOG并合理利用DPBA的蓝色发光，可以实现_0.16 -MOG^材料。
