antibiotics, tetracycline (TC) and secnidazole (SD). The mechanistic investigations of this luminescence quenching suggest that this might be primarily occurring via the Fourier resonance energy transfer (FRET) and photoinduced electron transfer (PET) mechanisms, which might be assisted by the competitive absorption and host–guest interactions. The π-electron-rich framework structure of sensor Zn-MOF activates
使用新型连接基L 4-py 2,7 通过溶剂热法构建了化学式为 [Zn( L 4-py )(bdc)}·DMF] n ( Zn-MOF ) 的特殊锌(II)-有机骨架-双(3-(吡啶-4-基乙炔基)苯基)苯并[lmn][3,8]菲咯啉-1,3,6,8(2 H ,7 H )-四酮},共配体H 2 bdc (1, 4-苯二甲酸)和 ZnBF 4 · x H 2 O。配体L 4-py是在 NDA(1,4,5,8-萘四甲酸二酐)核与 3-(pyridin-4-ylethynyl) 功能化后制备的)苯基。单晶X射线分析表明, Zn-MOF表现出全面的三维(3D)框架结构和特征(4)连接的单节直径; 4/6/c1; sqc6 拓扑,具有点符号 6 6 } 和二维 (2D) + 2D、并行多连接。值得注意的是, Zn-MOF在水和甲醇溶剂中表现出优异的荧光现象和稳定性,并被用作多功能传感器,表现出
