Fe N-Heterocyclic Carbene Complexes as Promising Photosensitizers

Yizhu Liu

The photophysics and photochemistry of transition metal complexes (TMCs) has long been a hot field of interdisciplinary research. Rich metal-based redox processes, together with a high variety in electronic configurations and excited-state dynamics, have r ...

Supramolecular gels based on boronate esters and imidazolyl donors

Rosario Scopelliti, Kay Severin, Nicolas Luisier

Dative boron–nitrogen bonds can be used for the controlled assembly of boronate esters and N-donor ligands. So far, most investigations have focused on crystalline assemblies. In contrast, there are very few reports about soft materials based on dative B–N ...

Transient versus Static Electron Spin Relaxation in Mn2+ Complexes Relevant as MRI Contrast Agents

Lothar Helm

The zero,-field splitting (ZFS) parameters of the Mn(EDTA)(H2O).2H(2)O. and [Mn(MeNO(2)A)(H2O)].2H(2)O systems were estimated by using DFT and ab initio CASSCF/NEVPT2 calculations (EDTA = (ethane-1,2-41bis(azanetriy1))tetraatetate; MeNO2A = 2,2'-(7-m ...

Molecular lanthanide single-ion magnets: from bulk to submonolayers

Jan Gui-Hyon Dreiser

Single-ion magnets (SIMs) are mononuclear molecular complexes exhibiting slow relaxation of magnetization. They are currently attracting a lot of interest because of potential applications in spintronics and quantum information processing. However, exploit ...

Design of Single-Molecule Magnets: Insufficiency of the Anisotropy Barrier as the Sole Criterion

Jan Gui-Hyon Dreiser

Determination of the electronic energy spectrum of a trigonalsymtnetry mononuclear Yb3+ single-molecule magnet (SMM) by highresolution absorption and luniinescente spectroscopies reveals that the first excited electronic doublet is placed nearly 500 cm(-1) ...

Exploring Ligand Affinities for Proteins by NMR of Long-Lived States

Roberto Buratto

The detection of molecules that can bind to active sites of protein targets and the measurement of their affinities is a promising application of NMR. Nowadays, the screening of drug candidates is routinely done by NMR in pharmaceutical industry. We have p ...

Origin of Perpendicular Magnetic Anisotropy and Large Orbital Moment in Fe Atoms on MgO

Harald Brune, Stefano Rusponi, Marina Pivetta, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Luca Gragnaniello, Giulia Elisabetta Pacchioni

We report on the magnetic properties of individual Fe atoms deposited on MgO(100) thin films probed by x-ray magnetic circular dichroism and scanning tunneling spectroscopy. We show that the Fe atoms have strong perpendicular magnetic anisotropy with a zer ...

Interplay between spin-orbit coupling and crystal-field effect in topological insulators

Oleg Yazyev, Hyungjun Lee

Band inversion, one of the key signatures of time-reversal invariant topological insulators (TIs), arises mostly due to the spin-orbit (SO) coupling. Here, based on ab initio density-functional calculations, we report a theoretical investigation of the SO- ...

Bicyclic Peptides Conjugated to an Albumin-Binding Tag Diffuse Efficiently into Solid Tumors

Christian Heinis, Alessandro Angelini, Sandeep Raghunathan, Lisa Pollaro, Julia Morales Sanfrutos

Monoclonal antibodies have long in vivo half-lives and reach high concentrations in tumors but cannot access all regions in the tissue, whereas smaller ligands such as peptides distribute better but are limited by low concentrations due to fast renal clear ...

Tuning the metal-insulator transition in NdNiO3 heterostructures via Fermi surface instability and spin fluctuations

Joël Mesot, Zoran Ristic

We employed in situ pulsed laser deposition (PLD) and angle-resolved photoemission spectroscopy (ARPES) to investigate the mechanism of the metal-insulator transition (MIT) in NdNiO3 (NNO) thin films, grown on NdGaO3(110) and LaAlO3(100) substrates. In the ...

Single-Molecule-Magnet Behavior in Mononuclear Homoleptic Tetrahedral Uranium(III) Complexes

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

The magnetic properties of the two uranium coordination compounds, [K(18c6)][U(OSi-((OBu)-Bu-t)(3))(4)] and [K(18c6)][U(N(SiMe3)(2))(4)], both presenting the U-III ion in similar pseudotetrahedral coordination environments but with different O- or N-donor ...

Synthesis, structural determination, theoretical studies and catalytic activity of Mn(II) complex of N-isonicotinyl phosphoric triamide ligand

Farzaneh Fadaei Tirani, Kurt Schenk

synthesized and characterized by H-1, C-13, P-31 NMR and IR spectroscopies. The reaction of MnCl2 center dot 4H(2)O with L led to the formation of a new 3D system {MnL2Cl2}(n)center dot 34CH(3)OH (C-1). X-ray crystallographic data revealed that the ligand ...

Neutron spectroscopic study of crystal-field excitations and the effect of the crystal field on dipolar magnetism in LiRF4 (R = Gd, Ho, Er, Tm, and Yb)

Henrik Moodysson Rønnow, Peter Babkevich, Bastien Dalla Piazza, Ivan Kovacevic

We present a systematic study of the crystal-field interactions in the LiRF4 (R = Gd, Ho, Er, Tm, and Yb) family of rare-earth magnets. Using detailed inelastic neutron scattering measurements, we have been able to quantify the transition energies and wave ...
