| Abstract |
Ligand-based redox-active coordination networks1 have recently attracted considerable attention as potential materials. Organic mixed-valence (MV) ligands may serve as a new functional component for coordination networks, but, to the best of our knowledge, reports on coordination networks composed of such MV ligands remain elusive.2 Therefore, the multi-redox-active/multi-interactive ligand 5,5',8,8'-tetra(4-pyridyl)-2,2'-(1,4-phenylene)bis-1H-perimidine (H2TPP) was synthesized and characterized. The multiple redox states of H2TPP including two MV states were confirmed by cyclic voltammetry (CV), UV-vis-NIR spectroscopy and ESR spectroscopy. As H2TPP is only sparingly soluble in organic solvents, we developed a new method for the preparation of single crystals of Cd-TPP network, i.e., a solvent-free solid-liquid interface reaction between H2TPP and molten metal ions. The redox properties of the Cd-TPP network were investigated by a solid-state CV and ESR measurements.
