Addition of electron-withdrawing substituents (Cl, CN) to tetrapyrazinoporphyrazines in TPyzPzCl8 and TPyzPz(CN)8 must shift their reduction potentials to more positive values even in comparison with TPyzPz [26]. In this work we synthesized and studied crystal structures, optical and magnetic ...
Here we demonstrate a Lewis-acid coordinated PEO-based electrolyte to achieve high-energy 4.8 V-class batteries. The strongly electronegative EO chains are captured by introducing Mg2+and Al3+with strong electron-withdrawing capability to weaken its solvating ability for high valence Ni at high v...
If one arm of the cruciform is substituted with electron-donating groups and the other with electron-withdrawing groups, their HOMO and LUMO are localize along the electron-rich and electron-poor axes, respectively. This spatial isolation of FMOs makes the intramolecular charge transfer absorption ...

It is demonstrated that the redox property of ceria is greatly affected due to the strong electron-withdrawing effect from the sulfate group (acid sites), which in turn increase the energy barrier for oxygen vacancy formation, weakens the ability for NO Declaration of Competing Interest The ...
The strong adsorption of benzene is ascribable to the strong Lewis acidity (electron withdrawing nature) of Co held by the ion exchange site of MFI zeolite [27]. Many kinds of noble metals showed activity loaded on the MFI zeolite for the benzene methylation with methane, but the side react...
(ii) the chlorine functional group of 4CP is an electron-withdrawing group, so the reaction affinity with the membrane polymer might dominate, (iii) water solubility is generally correlated with log Kow, thus suggesting that the adsorption capacity of 4CP onto the RO membrane increased with ...
