Effects of intervalence charge transfer interaction between π-stacked mixed valent tetrathiafulvalene ligands on the electrical conductivity of 3D metal-organic frameworks.

Results and discussions Syntheses and crystal structures of MOFs To take advantage of facile aerobic oxidation of electron-rich TTFTC to TTFTC ̇ + radical cation and the subsequent TTFTC/TTFTC ̇ + IVCT interaction that can promote long-range charge delocalization, herein, we have constructed a family of TTFTC-based MOFs, in which the π–π-distances, the degree of π-overlap, and the amount of TTFTC ̇ + radical cations varied systematically, showing a clear trend that commensurately influenced their band gaps and electrical conductivity.
