Synthesis, crystal structures, and fluorescence properties of porphyrin alkaline earth MOFs

Two porphyrin based alkaline earth MOFs [Sr4(TCPP)2(DMF)8]n (1) and [Ba4(TCPP)2(DMF)8]n (2) constructed from tetra(4-carboxyphenyl)porphyrin display a 3D supramolecular network isomorphous structure and exhibit interesting fluorescence properties.280
