Intramolecular Charge-Transfer Dynamics in Covalently Linked Perylene−Dimethylaniline and Cyanoperylene−Dimethylaniline

Natalie Renuka Banerji, Eric Vauthey

The excited-state dynamics of covalently linked electron donor−acceptor systems consisting of N,N-dimethylaniline (DMA) as electron donor and either perylene (Pe) or cyanoperylene (CNPe) as acceptor has been investigated in a large variety of solvents, inc ...

Observing molecular structure changes and dynamics in polar solution

Majed Chergui, Wojciech Gawelda

A review is presented concerning the exploitation of spectral information carried by probe pulse. The method reviewed allow observing changes and dynamics of the solute mol. structure in polar solvents. ...

Springer2007

This thesis presents a comparative study of the ultrafast solvation dynamics of liquids in bulk conditions, and at the interfaces of metal-IV oxides (specifically TiO2 and ZrO2), using ultrafast spectroscopy techniques. In the first part of the thesis we r ...

Organometallic Receptors for Biologically Interesting Molecules

Kay Severin

Trinuclear organometallic macrocycles are able to complex amino acids and peptides in aqueous solution. The complexation, which is driven by hydrophobic and π − π interactions, induces a large shift of the 1H NMR signals of the guest. The organometallic ho ...

Optical properties of molecules in solution via hybrid TDDFT/MM simulations

Ursula Röthlisberger

The optical properties of mols. in complex environments were studied within hybrid time-dependent d. functional theory / mol. mechanics (TDDFT/MM) simulation studies. The potential energy surface in the excited state is described within time-dependent d. f ...

Solvatochromic Analysis of Partition Coefficients in the o-Nitrophenyl Octyl Ether (o-NPOE)/Water System

Hubert Girault, Pierre-Alain Carrupt, Natalie Muller

The objective of this study was to unravel the structural properties responsible for the partitioning of solutes in o‐nitrophenyl octyl ether (o‐NPOE)/H2O, a new solvent system for the determination of the partition coefficients of ions. A set of 88 compou ...
