The excited-state dynamics of a series of electron donor−acceptor bridged systems (DABS) consisting of a boron−dipyrromethene chromophore covalently linked to a dinitro-substituted triptycene has been investigated using femtosecond time-resolved spectrosco ...
A series of lanthanide complexes [LnClx(bpy)y(H2O)z]Cl3-x(H2O)n(EtOH)m (Ln ) Eu, Gd, Tb; x ) 1, 2; y ) 1, 2; z ) 2-4) with different numbers of 2,2′-bipyridine (bpy), chloride ions, and water molecules in the inner coordination sphere were synthesized and ...
The synthesis of [PPN][IrRu3(CO)13] and [PPN][IrOs3(CO)13] from the reaction of [PPN][Ir(CO)4] with M3(CO)12 (M = Ru or Os) is discussed. [PPN][IrRu3(CO)13] is a red-brown microcryst. powder, while [PPN][IrOs3(CO)13] is an orange-red microcryst. powder. Bo ...
The fs-time-resolved study of a small UV dye in different solvents with fluorescence up-conversion and photon-echo techniques in the UV range provides new insight in cooling relaxation and solvation dynamics of non-polar molecules in polar solvents. ...

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 ...
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 ...
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 ...
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 ...
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 ...
