Since forms I鈥揑II differ both in oxidation state and structural features, a simple method is proposed to correlate the oxidation states of these ligands with their structural parameters, thus allowing the determination of the oxidation state on the basis of crystallographic data. By this procedure...
The possibility of changing the reactivity of organometallic and coordination compounds by changing the magnetic state due to oxidation of the redox-active phenolic group in the ligand is demonstrated. It is proposed to use ligand oxidation as a method for intramolecular activation of metal complexes....
bicomponent excitation and promote the rapid charge transfer and separation to form the electron–hole pairs of BTTD•−and 9-AC•+under light illumination. The motifs in the excited state can quickly complete oxygen reduction to superoxide radical (O2•−) and C(sp3)–H bond activation...

Each of these states can be the electronic ground state. They differ in the symmetry of the singly occupied MO, which, in each case, has a predominant Cr 3d character. While the spin density is localized mostly on the Cr atom, the charge on Cr is nearly the same in the neutral and ...
A new series of red phosphors based on Eu3+-doped yttrium cerate [Y1.9Ce2O7:0.1Eu3+, Y2Ce1.9O7:0.1Eu3+and Y2Ce2xO7:xEu3+(x= 0.05, 0.10, 0.15, 0.20, 0.25 and 0.50)] was preparedviaa conventional solid-state method. The influence of the substitution of Eu3+at the aliovalent...
A specific example of an indirect measurement based upon equilibrium concentrations is given below where the midpoint potential of the Mn-cofactor of modified reaction centers is determined by monitoring the oxidation state of P865. 2.2. Midpoint potentials of hemes Hemes are porphyrins with a ...

10). We find that Co2.75Fe0.25O4/Co(Fe)OxHy consistently delivers higher specific activity (~1 order of magnitude) than Co0.9Fe0.1OOH at ~1.58 V. In addition, as compared with other well-known state-of-art OER catalysts, the TOF of Co2.75Fe0.25O4/Co(Fe)OxHy on a per-surface-...
With improved luminance but lower current density, the EQE of QD-LEDs with PBO reaches a value of 23%, which is among the best-performing reported values and is about two times higher than that of the device without PBO (Fig. 2c), making this device state-of-the-art solution-processed...
