Toward Practical Aluminum Organic Batteries Featuring Covalent Organic Framework

open access: yesChemSusChem, EarlyView.
This study (re)evaluates the electrochemical performance of β‐ketoenamine‐linked anthraquinone‐based covalent organic framework (DAAQ‐TFP‐COF) as a cathode for aluminum batteries. Following voltage window optimization, surface and bulk analyses identified monovalent AlCl2+ as the coordination species.

Highly Efficient Simultaneous Photocatalytic Reduction of CO2 and O2 from Air Using Conjugated Microporous Polymers with Ionic Imidazolium Sites

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, we reported the rational design of two ionic conjugated microporous polymers for efficient simultaneous photocatalytic reduction of CO2 and O2 from air under mild conditions. Efficient photocatalytic reduction of CO2 is crucial to decrease the atmospheric concentration of CO2.

Variable Coordination of Peroxide in a Dinuclear Copper Mono‐Oxygenase Model Complex Supported by a Pyridazine‐Bridged Ligand

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Variable coordination of peroxide: The reaction of the Cu(I) complex‐based on the BPMPD ligand with O2 at low temperatures initially led to a μ‐1,2 peroxo species (Cu2O2). By addition of an acid (lutidinium triflate), this species can be reversibly converted into a μ‐1,1‐hydroperoxo complex, which is monitored using UV/Vis spectroscopy and X‐ray ...

Electrochemical Studies of Benzoquinone, Hydrobenzoquinone, Diphenoquinone and Hydrodiphenoquinone‐Based Compounds

open access: yesElectrochemical Science Advances, EarlyView.
The advantages of organic redox mediators over traditional inorganic counterparts are availability; they may in the future enlarge their applicability in all systems involving electron transfer during electrochemical processes. Several quinones, diphenoquinones and respective reduced forms, hydrobenzoquinones and hydrodiphenoquinones, were synthesized,
