N-Methylformamide (NMF) has been recognized as one of the most important industrially relevant solvents and a crucial intermediate used in industrial processes. However, indiscriminate use of NMF has been perceived as a threat to sustainable development owing to the lack of effective monitoring. In this study, a bimetallic lanthanide metal–organic framework (LMOF) with a fast response time and high sensitivity for monitoring of NMF is designed and fabricated, which also exhibits strong fluorescence. The response emission signals toward NMF range from red to green and are significantly correlated with the increase in the solvent concentration of NMF. Considering the fast response and excellent sensitivity results, a logic gate with AND functions for NMF is constructed. Using NMF and 300 nm as inputs, the output signals can be directly visualized by perceiving the green light at 544 nm of the sensor. Thus, such logic gates hold great promise for application in intelligent solvent diagnostics. In conclusion, we have constructed a hydrothermally robust, luminescent [Eu0.1Tb1.9(FDA)3(DMF)2]·2DMF (1) based sensor integrated with a logic gate capable of detecting NMF by intelligent discrimination.

具有逻辑门操作功能的自校准双金属镧系金属有机发光传感器，用于检测N-甲基甲酰胺†
ñ-甲基甲酰胺（NMF）被公认为是最重要的与工业相关的溶剂之一，并且是工业过程中使用的重要中间体。但是，由于缺乏有效的监测，滥用NMF被视为对可持续发展的威胁。在这项研究中，设计并制造了具有快速响应时间和对NMF监测的高灵敏度的双金属镧系金属-有机骨架（LMOF），并且还具有较强的荧光性。朝向NMF的响应发射信号范围从红色到绿色，并且与NMF溶剂浓度的增加显着相关。考虑到快速响应和出色的灵敏度结果，构建了具有“与”功能的NMF逻辑门。使用NMF和300 nm作为输入，通过感知传感器在544 nm处的绿光，可以直接可视化输出信号。因此，这种逻辑门在智能溶剂诊断中具有广阔的应用前景。总之，我们构建了一种水热稳健的，发光的[Eu基于0.1 Tb 1.9（FDA） 3（DMF） 2 ]·2DMF（ 1）的传感器集成了逻辑门，该逻辑门能够通过智能识别来检测NMF。
