“…The electron-deficient structure of boric acid binds to the electron donor system of N and O atoms in 1 by intermolecular hydrogen bonding, resulting in phototransfer of electrons and increased fluorescence intensity. 31 Above all, the fluorescence enhancement mechanism of Al 3+ and B 4 O 7 2− can be ascribed to the photoinduced electron transfer (PET) mechanism.…”

“…The structure of 1 were solved by direct methods using SHELXS-97, and the non-hydrogen atoms were refined by full-matrix least-squares techniques (on F 2 ) to convergence using SHELXL-2014 with anisotropic displacement parameters. 31 Hydrogen atoms were located on a difference Fourier map and introduced into the calculations as a Riding model with isotropic thermal parameters.…”

Acetate‐bridged binuclear Co(II) and Ni(II) complexes, [Co2(L)(μ‐OAc)(EtOH)] (1) and [Ni2(L)(μ‐OAc)(EtOH)] (2) were synthesized via the reaction of a new bis(salamo)‐like ligand with two different metal(II) acetates. X‐ray single crystal diffraction analyses showed that two metal(II) ions (Co or Ni) occupy two sets of N2O2 cavities, respectively. The acetate group bridges the two metals, and the ethanol oxygen atom participates in the coordination. Furthermore, UV–vis titration experiments clearly indicated that the complexation between H3L and M(II) ions leads to the 1:2 complexes [(L)M2]+ through a highly synergistic process. Bond valence sum (BVS) calculations exhibited that the Co(II) and Ni(II) ions are divalent. Secondly, the ligand H3L highest occupied molecular orbital–lowest unoccupied molecular orbital (HOMO‐LUMO) gap analysis and surface electrostatic potential were theoretically analyzed by theoretical calculation (density functional theory), and the reactivity of M(II) ions and the ligand in the complex formation process was demonstrated. Finally, the microscopic properties of the complexes were deeply understood through the calculation of the weak intramolecular interactions and the unstressed regions outside the complexes.
