摘 要：An efficient photosensitizing of[γ-SiWVO]based MOF(POM-Cd-TPPA)within cage and channel was achieved via in situ synthesis under solvothermal conditions for light-driven acceleration ofα-site C-Harylation of amino[1].Single-crystal structural analysis revealed that POM-Cd-TPPA crystallized in a space group *** crystallographically independent Cdis connected by deprotonated[γ-SiWVO]polyoxoanions to generate a 3D *** ligands embedinto the structure,stabilizing the framework and generating a huge *** Cd atom adopted a six-coordinated octahedral geometry with four nitrogen atoms from four TPPA ligands positioned in the equatorial plane and two terminal oxygen atoms from two deprotonated[γ-SiWVO]polyoxoanions occupied in the axial *** polyoxoanion is connected with four Cadmiun ions throw four terminal oxygen atoms from the POM,and each TPPA is connected with three Cadmiun ions throw three Nitrogen atoms of the ligand(Figure.1).Detailed structural analysis using the PLATON software suggests that the effective free volume of POM-Cd-TPPA without the sovlent molecules is42.8%.The pores and caves of POM-Cd-TPPA are thus able to adsorb terephthalonitrile and its derivatives which are the substrates for the C-H arylation of aromatic tertiary amines(Table 1).
