“…1 These include gas and small molecule storage, [2][3][4][5] separation processes, 6,7 catalysis, 8,9 chemical sensing, [10][11][12] structural determination, 13 as well as electronic devices. [14][15][16][17] However, the redox and electronic properties of three dimensional MOFs have attracted relatively less attention in comparison with their adsorption properties. 18 The physical and chemical characteristics of ligands play a crucial role in dictating the properties of novel functional MOFs.…”

Four new polymeric metal compounds based on the redox-active tetrathiafulvalene-tetrabenzoate ligand and different divalent cations (Co(II), Cd(II), bipyridine, Bpea = 1,2-bis(4-pyridyl)ethane), were synthesized and characterized. The versatile redox-active tetracarboxylate ligand was coordinated to divalent metal ions in a multidentate fashion, forming different structures for complexes 1-4. Complex 1 exhibits a one-dimensional chain structure, whereas the three-fold interpenetrating 3,4L13 net was observed in complex 2. Importantly, complex 3 displays (3,8)-connected tfz-d net and complex 4 features new (4,8)-connected three-dimensional topological network with a point symbol of (4 4 .6 2 ) 2 (4 8 .6 4 .8 16 ). The solid-state electrochemical properties and gas adsorption behaviors of 3 and 4 were subsequently investigated. Due to the incorporation of π-electron conjugated TTF rings into porous metal-organic frameworks, complexes 3 and 4 exhibit two reversible oxidation processes and adsorption selectivity for CO 2 over N 2 .These compounds enrich the study of redox-active porous materials.

For electrochemical device applications metal organic frameworks (MOFs) must exhibit suitable conduction properties. To this end, we have performed computational studies of intermolecular charge transfer in MOFs consisting of hexa-Zr IV nodes and tetratopic carboxylate linkers. This includes an examination of the electronic structure of linkers that are derived from tetraphenyl benzene 1, tetraphenyl pyrene 2 and tetraphenyl porphyrin 3 molecules. These results are used to determine charge transfer propensities in MOFs, within the framework of Marcus theory, including an analysis of the key parameters (charge transfer integral t, reorganization energy λ and free energy change ∆G 0 ), and evaluation of figures of merit for charge transfer based on the chemical structures of the linkers. This qualitative analysis indicates that delocalization of the HOMO/LUMO on terminal substituents increases t and decreases λ, while weaker binding to counterions decreases ∆G 0 , leading to better charge transfer propensity. Subsequently, we study hole transfer in the linker 2 containing MOFs, NU-901 and NU-1000, in detail and describe mechanisms (hopping and superexchange) that may be operative under different electrochemical conditions. Comparisons with experiment are provided whereavailable. Based on the redox and catalytic activity of nodes and linkers, we propose three possible schemes for constructing electrochemical devices for catalysis. We believe that the results of this study will lay the foundation for future experimental work on this topic.
