Study of the pO2-sensitivity of the dendrimeric and free forms of Pd-meso-tetra(4-carboxyphenyl)porphyrin, incorporated or not in chitosan-based nanoparticles

Hubert van den Bergh, Georges Wagnières, Peter Käuper, Patrycja Nowak-Sliwinska

The concentration of oxygen and its rate of consumption are important factors in certain medical treatments, such as radiotherapy and photodynamic therapy (PDT). Measuring the tissue concentration of oxygen or its partial pressure (pO2) can be achieved by ...

A Multitechnique Approach to Spin-Flips for Cp2Cr(II) Chemistry in Confined State

David Lyndon Emsley

Paramagnetic solid-state NMR, extended X-ray absorption fine structure (EXAFS), and Raman spectroscopies, along with detailed quantum mechanical calculations performed with different density functional theory (DFT) functionals, are successfully applied to ...

Vibrational coherences and relaxation in the high-spin state of aqueous [Fell(bpy)3]2+

Majed Chergui, Frank van Mourik, Andrea Cannizzo, Amal El Nahhas, Cristina Consani, Mirabelle Prémont-Schwarz

Dizzy cooling: Femtosecond excitation of the singlet states of aqueous [FeII(bpy)3]2+ (bpy=2,2-bipyridine) leads to the formation of a vibrationally hot quintet state that exhibits wave-packet dynamics arising from a chelate-ring and bending mode. The vibr ...

Triplet State Imaging

Dimitri Nestor Alice Van De Ville, Theo Lasser, Boris Hinz, Iwan Märki, Thiemo Spielmann, Aurélie Formey de Saint Louvent

We present a functional imaging method based on triplet state kinetics. The triplet state of many known fluorophores shows a triplet lifetime typically in the order of ~10e-6 – 10e-3 s, 3-6 orders of magnitude longer than the associated fluorescence single ...

Triplet Imaging by Modulated Excitation

Dimitri Nestor Alice Van De Ville, Theo Lasser, Kai Johnsson, Boris Hinz, Thiemo Spielmann, Aurélie Formey de Saint Louvent

We present a functional imaging method based on triplet state kinetics. The triplet state of many known fluorophores show a triplet lifetime typically in the order of ~10e-6 – 10e-3 s, 3-6 orders of magnitude longer than the associated fluorescence singlet ...

Triplet imaging contrast by modulated excitation

Theo Lasser, Marcel Leutenegger, Boris Hinz, Thiemo Spielmann

A novel imaging method employing the different kinetics of the energetic states of fluorescent markers is presented, where the contrast depends on the triplet kinetics. An attractive feature of triplet states is their long lifetime, rendering them highly s ...

Structural Determination of a Short-Lived Excited Iron(II) Complex by Picosecond X-Ray Absorption Spectroscopy

Majed Chergui, Wojciech Gawelda, Van Thai Pham

Structural changes of the Fe(II)-tris-bipyridine ([FeII(bpy)3]2+) complex induced by ultrashort pulse excitation and population of its short-lived (?0.6 ns) quintet high spin state were detected by picosecond x-ray absorption spectroscopy. The structural r ...

A Novel Strategy for the Design of 8-Hydroxyquinolinate- Based Lanthanide Bioprobes That Emit in the Near Infrared Range

Jean-Claude Bünzli, Caroline Vandevyver

A new polydentate tripodal ligand T2soxMe was synthesized to take advantage of the chelating effect of tridentate 8- hydroxyquinolinate subunits. Potentiometric and spectrophotometric titrations reveal seven pKa values of between 3.7 and 10.2. In water, th ...

Light-induced spin crossover probed by ultrafast optical and X-ray spectroscopies

Majed Chergui, Andrea Cannizzo, Wojciech Gawelda, Van Thai Pham, Amal El Nahhas, Renske Marjan van der Veen

The photoinduced energy and structural relaxation of aq. iron(II)-tris-bipyridine ([FeII(bpy)3]2+), upon excitation into its singlet metal-to-ligand charge transfer (1MLCT) band, and the population of its short-lived (?0.6 ns) high-spin excited state have ...
