A new type of 2D metal-organic framework (MOF), namely Cu-MOF, was constructed from Cu(NO)·3HO and the novel ligand 1,4-bis(4-naphthoic acid)benzene. The C-Hπ interactions in the Cu-MOF effectively reduced aggregation-caused quenching (ACQ) due to restrictions in intramolecular motion (RIM), increased fluorescence, and controlled crystal packing properties, resulting in low dimensional parallelogram channels and a responsive "turn-on" fluorescence. The activated Cu-MOF exhibited excellent chemical sensing properties to various volatile organic compounds (VOCs) and showed excellent recyclability.
一种新型二维金属有机骨架（MOF），即 Cu-MOF，由 Cu(NO)·3HO 和新型配体 1,4-双（4-萘甲酸）苯合成。Cu-MOF 中的 C-Hπ 相互作用有效地减少了由于分子内运动受限（RIM）而引起的聚集猝灭（ACQ），增加了荧光，并控制了晶体堆积特性，从而产生了低维平行四边形通道和响应性“开启”荧光。活化的 Cu-MOF 对各种挥发性有机化合物（VOCs）表现出优异的化学传感性能，并且具有出色的可回收性。
