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 ...

Designing Simple Tridentate Ligands for Highly Luminescent Europium Complexes

Rosario Scopelliti, Jean-Claude Bünzli, Svetlana Eliseeva

A series of tridentate benz- ACHTUNGTRENUNGimidazole-substituted pyridine-2-carboxylic acids have been prepared with a halogen, methyl or alkoxy group in the 6-position of the benzimidazole ring, which additionally contains a solubilising N-alkyl chain. Th ...

Non-adiabatic Dynamics Using Time-Dependent Density Functional Theory: assessing the Coupling Strengths

Ursula Röthlisberger, Ivano Tavernelli, Enrico Marko Tapavicza

Light-driven reactions constitute an important class of processes in physics, chemistry, and biology. The development of accurate and efficient computational tools for the study of excited states dynamics has thus become of primary importance. Recently, we ...

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 ...

Femtosecond Fluorescence and Intersystem Crossing in Rhenium(I) Carbonyl-Bipyridine Complexes

Majed Chergui, Andrea Cannizzo, Amal El Nahhas

Ultrafast electronic-vibrational relaxation upon excitation of the singlet charge-transfer b1A' state of [Re(L)(CO)3(bpy)]n (L = Cl, Br, I, n = 0; L = 4-Et-pyridine, n = 1+) in acetonitrile was investigated using the femtosecond fluorescence up-conversion ...

Extending the Scope of Singlet-State Spectroscopy

Geoffrey Bodenhausen, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

Different decoupling sequences are tested - using various shaped radio-frequency (RF) pulses - to achieve the longest possible lifetimes of singlet-state populations over the widest possible bandwidths, that is, ranges of offsets and relative chemical shif ...

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 ...

Molecular Properties Determined from Relaxation of Long-Lived Spin States

Geoffrey Bodenhausen, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

The populations of long-lived spin states, in particular, populations of singlet states that are comprised of antisymmetric combinations of product states, ∣αIβS⟩−∣βIαS⟩, are characterized by very long lifetimes because the dipole-dipole interaction betwee ...
