These analogues, with a series of functional groups (NO2, SH, F, Cl, Br, CH3, OH, NH2, phenyl and H), mainly on the C2 position of the imidazolate linker, were simulated for CO2 adsorption. Strong electron with

2a). Both electron-donating and electron-withdrawing groups can be introduced to the benzene ring of the 2-iodophenyl allenyl ether substrate, with the target benzofuran products 3 afforded in moderate to good yields (Figs. 2a and 3b–j). Substituents can also be installed on the allenyl ...
Moreover, the large TPA cross-sections are usually achieved based on the intramolecular charge-transfer (CT) processes in complex molecular architectures with electron donating and withdrawing groups [[12], [13], [14]]. The large dipole moment often results in a nonradiative or inefficient ...
On demand: The first example of the title reaction involving cyclic ketones and 尾,-unsaturated -ketoesters has been achieved using the novel enamine/metal Lewis acid bifunctional catalysis (see scheme; Tf=trifluoromethanesulfonyl). Enones with both electron-withdrawing and electron-donating groups at...
//en.wikipedia.org/wiki/Radical-nucleophilic_aromatic_substitution. This reaction takes places only after initial homolysis of a carbon-halide bond on an aryl halide. This reaction is known to be promoted by electron withdrawing groups, and retarded by electron donating groups, both on the ...

Transient absorption spectroscopy(TA) measurements confirmed how the electron-withdrawing and electron-donating groups can efficiently turn the hot carriers(HCs) cooling and injection, and interface recombination in the device. We found that NSC-passivated perovskite samples exhibit faster hot-carriers(HCs...
Especially, the influence of electron-withdrawing/-donating groups on the carrier dynamics in device has not been studied. PSCs photovoltaic properties directly interact with the excited charge-carriers (electrons and holes) interaction through dielectric screening. Therefore, fully understanding of the ...
Increased stability of a carbon-centred radical resulting from the combined effect of electron-withdrawing and electron-donating groups attached to the radical centre. Proton-coupled electron transfer (PCET). Class of chemical reactions that involves the transfer of an electron and proton in a concert...
