Interdigitated conducting tetrathiafulvalene-based coordination networks

Abstract

The electronic conductivity of two isostructural interdigitated coordination polymers based on a novel tetrathiafulvalene derivative and M(NCS)2 nodes (M = Fe, Co) is enhanced upon surface oxidation of the crystals by iodine.

Preliminary chemical reduction for synthesizing a stable porous molecular conductor with neutral metal nodes

“…This approach is advantageous due to the variety of useable ligands and the availability of single crystals. [14][15][16][17][18][19] However, only a few MOFs possess sufficient amounts of conduction carriers in the through-space conduction pathways. [20][21][22] Incorporating numerous conduction carriers was possible by applying an electrocrystallization method, which is typically used for the preparation of molecular conductors.…”

Coordination assemblies based on a flexible tetrathiafulvalene derivative

“…shown by powder X-ray diffraction. As a consequence, doping with iodine to promote TTF oxidation [23] and hence conductivity could unfortunately also not be further explored.…”

“…Carboxylic acids and pyridine groups have been extensively employed for such purposes affording MOFs with appealing physical properties. [11][12][13][14][15][16][17][18][19][20][21][22][23][24] In the vast majority of cases, the binding moieties are attached in a direct fashion to the TTF core thus providing rigidity to the ligand and hence a certain degree of predictability to the construction of CPs and MOFs, upon combining with metal nodes of known geometric preferences. Contrastingly, we have recently designed and synthesized the flexible TTF ligand bearing thiopyridyl units, TTF(S-4py)4 (Fig.…”
