A new type of 2D metal-organic framework (MOF), namely Cu-MOF, was constructed from Cu(NO3)2·3H2O 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.
