Abstract Polarization change induced by directional electron transfer attracts considerable attention owing to its fast switching rate and potential light control. Here, we investigate electronic pyroelectricity in the crystal of a mononuclear complex, [Co(phendiox)( rac -cth)](ClO 4 )·0.5EtOH ( 1 ·0.5EtOH, H 2 phendiox = 9, 10-dihydroxyphenanthrene, -cth racemic 5, 7, 12, 14-hexamethyl-1, 4, 8, 11-tetraazacyclotetradecane), which undergoes two-step valence tautomerism (VT). Correspondingly,...
To alleviate the energy and environmental crisis, in last decades, harvesting by utilizing optical control has emerged as a promising solution. Here we report polar crystal that exhibits photoenergy conversion storage upon light irradiation. The consists of dinuclear [CoGa] molecules, which are oriented uniform direction inside lattice. Irradiation with green induces directional intramolecular electron transfer from ligand to low-spin CoIII centre, resultant light-induced high-spin CoII...
Understanding the nature of metal–ligand bonding is a major challenge in actinide chemistry. We present new experimental strategy for addressing this using 3d4f resonant inelastic X-ray scattering (RIXS). Through systematic study uranium(IV) halide complexes, [UX6]2–, where X = F, Cl, or Br, we identify RIXS spectral satellites with relative energies and intensities that relate to extent uranium-ligand bond covalency. By analyzing spectra combination ligand field density functional theory...
Taking advantage of synchrotron light source methods, we present the geometric and electronic structure iron doped in lithium nitride.
X-ray absorption spectroscopy and dichroism are applied to probe the effect of 3d–4s mixing on electronic structure magnetism for linearly coordinated Mn, Fe, Co, Ni Cu.
