Conservation of vibrational coherence in ultrafast electronic relaxation: The case of diplatinum complexes in solution

Majed Chergui, Dominik Kinschel, Gerald Auböck, Roberto Monni, Kathrin Maria Aziz-Lange

We report the results of ultrafast transient absorption studies of tetrakis(l-pyrophosphito) diplatinate(II), Pt-2(mu-P(2)O(5)H2)(4) (Pt(pop)) and its perfluoroborated derivative Pt-2(mu-P2O5(BF2)(4) (Pt(pop-BF2)) in water and acetonitrile upon e ...

Nonadiabatic Dynamics with Spin-orbit couplings

Felipe Miraglia Franco de Carvalho

This thesis deals with the excited-states dynamics of molecules beyond the Bon-Oppenheimer approximation (nonadiabatic dynamics). The nuclei were always treated with classical mechanics while the electrons were treated quantum mechanically, using linear-re ...

Local Structures and Heterogeneity of Silica-Supported M(III) Sites Evidenced by EPR, IR, NMR, and Luminescence Spectroscopies

David Lyndon Emsley, Aaron James Rossini

Grafting molecular precursors on partially dehydroxylated silica followed by a thermal treatment yields silica-supported M(III) sites for a broad range of metals. They display unique properties such as high activity in olefin polymerization and alkane dehy ...

Atomic-Scale Imaging and Spectroscopy of Electroluminescence at Molecular Interfaces

Klaus Kern, Christoph Grosse

The conversion of electric power to light is an important scientific and technological challenge. Advanced experimental methods have provided access to explore the relevant microscopic processes at the nanometer scale. Here, we review state-of-the-art stud ...

Strongly Red-Shifted Photoluminescence Band Induced by Molecular Twisting in Cyanine (Cy3) Dye Films

Frank Nüesch, Roland Hany, Jakob Heier, Surendra Babu Anantharaman, Chuyao Peng

Cyanine dye molecules, used as monomers or in aggregate form, find interesting applications in optoelectronic devices. Among the various aggregate species incorporating organic dyes, centrosymmetric dimers are known as nonluminescent. They can act as excit ...

Tris-heteroleptic Iridium Complexes Based on Cyclometalated Ligands with Different Cores

Ivano Tavernelli, Yanouk Cudré

A series of tris-heteroleptic iridium complexes of the form [Ir(CN-1)(CN-2)(acac)] combining 2-phenyl pyridine (ppy), 2-(2,4-difluorophenyl)pyridine (dFppy), 1-phenylpyrazole (ppz), and 1-(2,4-difluorophenyl)pyrazole (dFppz) as the CAN ligands have b ...

Fluorescence Quenching in BODIPY Dyes: the Role of Intramolecular Interactions and Charge Transfer

Antonio Prlj, Laurent Alexis Clément Vannay

The fluorescence properties of the BODIPY dye and its two meso-substituted derivatives, tert-butyl- and phenyl-BODIPY, are rationalized. The non emissive behavior of the latter two are attributed to the energetically accessible low-lying conical intersecti ...

Skyrmion formation in a bulk chiral magnet at zero magnetic field and above room temperature

Henrik Moodysson Rønnow, Jonathan White

We report that in a β-Mn-type chiral magnet Co9Zn9Mn2, skyrmions are realized as a metastable state over a wide temperature range, including room temperature, via field cooling through the thermodynamic equilibrium skyrmion phase that exists below a transi ...

Spectral properties of a symmetric three-dimensional quantum dot with a pair of identical attractive delta-impurities symmetrically situated around the origin

Fabio Rinaldi

In this presentation, we wish to provide an overview of the spectral features for the self-adjoint Hamiltonian of the three-dimensional isotropic harmonic oscillator perturbed by either a single attractive delta-interaction centered at the origin or by a p ...
