摘要

A series of four porphyrin-alkaline earth metal-organic frameworks [Mg(HDCPP)(2)(DMF)(2)](n)center dot(H2O)(7n) (1), [Ca(HDCPP)(2)(H2O)(2)](n)(DMF)(1.5n) (2), [Sr(DCPP)(H2O)(DMA)](n) (3), and [Ba(DCPP)(H2O)(DMA)](n) (4) was isolated for the first time from solvothermal reaction between metal-free 5,15-di(4-carboxyphenyl) porphyrin (H2DCPP) and alkaline earth ions. Single-crystal X-ray diffraction analysis reveals the 2D and 3D supramolecular network with periodic nanosized porosity for 1/2 and 3/4, respectively. The whole series of MOFs, in particular, compounds 1 and 2 with intrinsic low molecular formula weight, exhibit superior adsorption performance for methylene blue (MB) with excellent capture capacity as represented by the thus far highest adsorption amount of 952 mg g(-1) for 2 and good selectivity, opening a new way for the potential application of the main group metal-based MOFs.
