Abstract:
1,10-Phenanthroline-5,6-dione (phendione)-based transition-metal complexes are known for their use in pharmacological and catalysis applications. However, their application in electrochemical energy storage has not been investigated thus far. Herein, the feasibility of employing phendione-transition-metal complexes was investigated for electrochemical charge storage by taking advantage of the reversible redox activity of both carbonyl groups and transition metal center, contributing to augmented charge storage. Interestingly, the chemistry of the counter ion in the studied complexes effectively tuned the solubility and improved the cycling stability. Although further studies are required to limit the solubility and active-species shuttle, this study explores the bottlenecks of phendione-transition-metal complexes as electrode materials for solid-electrode-format batteries.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
