Redox-Active Metal-Organic Frameworks with Three-Dimensional Lattice Containing the m-Tetrathiafulvalene-Tetrabenzoate
Metal-organic frameworks (MOFs) constructed by tetrathiafulvalene-tetrabenzoate (H(4)TTFTB) have been widely studied in porous materials, while the studies of other TTFTB derivatives are rare. Herein, the meta derivative of the frequently used p-H(4)TTFTB ligand, m-H(4)TTFTB, and lanthanide (Ln) met...

description | Metal-organic frameworks (MOFs) constructed by tetrathiafulvalene-tetrabenzoate (H(4)TTFTB) have been widely studied in porous materials, while the studies of other TTFTB derivatives are rare. Herein, the meta derivative of the frequently used p-H(4)TTFTB ligand, m-H(4)TTFTB, and lanthanide (Ln) metal ions (Tb(3+), Er(3+), and Gd(3+)) were assembled into three novel MOFs. Compared with the reported porous Ln-TTFTB, the resulted three-dimensional frameworks, Ln-m-TTFTB ([Ln(2)(m-TTFTB)(m-H(2)TTFTB)(0.5)(HCOO)(DMF)]·2DMF·3H(2)O), possess a more dense stacking which leads to scarce porosity. The solid-state cyclic voltammetry studies revealed that these MOFs show similar redox activity with two reversible one-electron processes at 0.21 and 0.48 V (vs. Fc/Fc(+)). The results of magnetic properties suggested Dy-m-TTFTB and Er-m-TTFTB exhibit slow relaxation of the magnetization. Porosity was not found in these materials, which is probably due to the meta-configuration of the m-TTFTB ligand that seems to hinder the formation of pores. However, the m-TTFTB ligand has shown to be promising to construct redox-active or electrically conductive MOFs in future work. |
