A novel photofunctional hybrid material of pyrene functionalized metal-organic framework with conformation change for fluorescence sensing of Cu2+

MIL-53-L was made from a metal-organic framework which was synthesized using pyrene-functionalized organic as building block. This ligand has framework construction, detecting and fluorophore parts. The flourescence property of MIL-53-L changed by space limitations within the metal organic frameworks structure to detect of Cu 2+ ion.
