    “…The structure contains two Co(II) centres with different octa­hedral environments, [Co(1)N(3)O(3)] and [Co(2)N(2)O(4)]. The O-donating 3-chloro­benzoate anions (3-Clbenz) act as the terminal ligands, while the N-donating 4,4′-bipy mol­ecules play the role of linkers. …”

    “…In summary, the introduction of an electron-donating group -NH(2) can promote the ESIPT reaction of DMA3HF, without changing the photophysical properties, while introducing the electron-withdrawing group -CN can greatly improve the absorption of DMA3HF in the ultraviolet band, but hinders the occurrence of the ESIPT reaction.…”

    “…The greatest plant uptake rates occurred with an electron-withdrawing functional group at the 2 position; however, uptake was still observed with an electron-donating group. An electron-donating group at the 1 position significantly slowed uptake for both benzimidazole- and benzotriazole-based molecules used in this study, indicating possible steric effects. …”

    “…The structure-activity relationship showed that the strength of PTP1B inhibitory activity was mainly related to the electron-donating group on its side chain. Molecular docking analysis suggested that its mechanism may be due to the formation of competitive hydrogen bonding between the electron-donating moiety and the Asp48 amino acid residues on the PTP1B protein.…”

    “…It is demonstrated here that tridentate imine ligands can control the nuclearity of copper(II) complexes based on the donor atoms present in the ligand. The N,N′,N′′-donating imine ligand led to a mononuclear compound, namely di­chlorido­[N,N-dimethyl-N′-(pyridin-2-yl­methyl­idene)ethane-1,2-di­amine]copper(II) monohydrate, [CuCl(2)(C(10)H(15)N(3))]·H(2)O, 1, while the N,N′,O-donating imine ligand produced a binuclear metal complex, namely μ(2)-chlorido-di­chlorido­(μ(2)-2-{[2-(di­methyl­amino)­ethyl]imino­methyl}phenolato)(N,N-dimethyl­ethylene­di­amine)­dicopper(II) 0.11-hydrate, [Cu(2)(C(11)H(15)N(2)O)Cl(3)(C(4)H(12)N(2))]·0.11H(2)O, 2. …”
