Abstract:
Metal-organic frameworks (MOFs) have emerged as structurally designable materials for lithium-ion batteries (LIBs) due to their tunable coordination architecture and functionality. Herein, we report a couple of isostructural MOFs of divalent cobalt (1) and zinc (2), [MII2(bdc)2(DABCO)]n, [bdcH2 = terephthalic acid, DABCO = 1,4-diazabicyclo[2.2.2]octane], and evaluate their lithium storage performance. Electrochemical properties and performance show that Co-MOF 1 has higher efficiency than the Zn congener, with an excellent specific capacity of 750 mAh g-1 after 10 cycles and last at 322 mAh g-1 after 200 cycles, which is a high electrochemical performance in specific capacity and rate cycle performance over the previous MOF-based materials. The ligand substitution at the metal centers of the MOFs triggered the single-crystal to single-crystal transformation toward corresponding [MII(H2O)(bdc)(DABCO)]n (1a and 2a) MOFs, which were investigated. First-principles computations revealed that the identity of the metal center critically governs the lithiation behavior of these MOFs.

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 eye.
