A novel MOF Bi-TCBPE ([Bi(TCBPE)(H₂O)]·(Me₂NH₂⁺)) based on 4′,4‴,4″‴,4‴‴-(ethene-1,1,2,2-tetrayl)tetrakis(([1,1′-biphenyl]-4-carboxylic acid)) has been synthesized and characterized by elemental analysis, powder X-ray diffraction, IR, UV–vis spectroscopy and thermogravimetry analysis, which exhibits strong emission (Φ_F = 76.96%) in methanol suspension.The photophysical process was analyzed by TRES. Structural analysis revealed that Bi-TCBPE showed a novel two-fold interpenetrated packing framework. Luminescence measurements indicate that the Bi-TCBPE sensor shows sensing behavior with “turn off” towards Fe³⁺ and “turn on” towards Cysteine (Cys) significantly. Bi-TCBPE as a luminescent sensor displays quenching effect towards Fe³⁺ detection in the interference of Fe²⁺. It also can be used for the quantitative determination of Fe³⁺ in serum. The results will provide a great possibility for the practical application of luminescent metal organic frameworks (LMOFs) in clinical detection.

一种新颖的MOF双TCBPE（[铋（TCBPE）（H ₂ O）]·（ME ₂ NH ₂ ⁺））的基础上4'，4'''，4“'''，4'''''' - （乙烯- 1,1，已合成并通过元素分析，粉末X射线衍射，IR，UV-vis光谱和热重分析对2，2-二丁基）四（（[[1,1'-联苯] -4-羧酸））进行了表征。展品强发射（Φ _˚F  = 76.96％）的甲醇悬浮液。光物理过程由TRES分析。结构分析表明，Bi-TCBPE显示出一种新型的两层互穿包装结构。发光测量表明，Bi-TCBPE传感器显示出对Fe ^3+呈“关闭”状态的感应行为并显着“转向”半胱氨酸（Cys）。Bi-TCBPE作为发光传感器在Fe ²⁺的干扰下对Fe ^3+的检测具有猝灭作用。它也可用于定量测定血清中的Fe ³⁺。该结果为发光金属有机骨架（LMOF）在临床检测中的实际应用提供了很大的可能性。
