Photostimulation responsive europium-based metal organic framework for orderly packaging tetrathiafulvalene object

The invention provides a photo-stimulus-responsive europium-based metal organic framework (TTF (at) Eu-MOF) for orderly packaging a tetrathiafulvalene guest through exploration of a synthesis method aiming at the scarcity of a photo-stimulus-responsive rare earth metal organic framework constructed by utilizing ordered packaging of the guest, and the photo-stimulus-responsive europium-based metal organic framework (TTF (at) Eu-MOF) for orderly packaging the tetrathiafulvalene guest is provided. The TTF (at) Eu-MOF is synthesized by taking self-prepared Eu-MOF as a precursor and soaking the precursor in a tetrathiafulvalene solution. Wherein TTF molecules are orderly arranged in pore channels of the framework and form rich pi... pi stacking interaction with a naphthalimide parent of the ligand. Under the stimulation of external light, ultraviolet and fluorescence signals of the TTF (at) Eu-MOF are changed, and the TTF (at) Eu-MOF shows obvious responsiveness and has the potential of being developed into a phot
