The advent of ultrafast laser spectroscopy has allowed entirely new possibilities for the investigation of the ultrafast photophysics of inorganic metal-based molecular complexes. In this review we show different regimes where non-Kasha behavior shows up. ...

A wide variety of physicochemical processes at a molecular level, in particular charge or energy transfer, electronic and vibrational relaxation, are at the origin of biological functionality of proteins and organometallic compounds. The work reported in t ...
The need for magnetic resonance imaging (MRI) contrast agents with improved relaxivity maintains the development of new Gd-III chelates as an intensive and demanding field of research. In this work, we introduce the new dimeric chelators bis{1,4,7,10-tetra ...
We described herein a simple approach for N-formylation with CO2 and hydrosilane reducing agents. Fluoride and hydroxide salts efficiently catalyzed the reaction, principally through activation of the hydrosilanes, which led to hydrosilane reactivities com ...
A series of eight Ru(II) heteroleptic complexes incorporating an ancillary [2,2′]bipyridine functionalised at the [4,4′] positions with one (M-type) or two (B-type) thienylenevinylenes (nTVs, n = 2 or 4) is reported. Three types of substitutions have been ...
Upon metal-metal contact, a transfer of electrons will occur between the metals until the Fermi levels in both phases are equal, resulting in a net charge difference across the metal-metal interface. Here, we have examined this contact electrification in b ...
Fijiolide A is a secondary metabolite isolated from a marine-derived actinomycete of the genus Nocardiopsis. It was found to significantly reduce the TNF-alpha induced activity of the transcription factor NF kappa B, which is considered a promising target ...
The preparation and characterization of a series of complexes of the Yb and Eu cations in the oxidation state II and III with the tetradentate N,O-donor tripodal ligands (tris(2-pyridylmethyl)amine (TPA), BPA(-) (HBPA=bis(2-pyridylmethyl)(2-hydroxybenzyl)a ...
Developing new strategies and methods to explore new dimensions of the chemical space represents an important goal for organic chemists. One particular synthetic approach that emerged in the last decades is Umpolung: the normal polarity of chemical functio ...
A new series of higher generation cationic N,N-chelating, ruthenium(II)-ethylene-glycol metallodendrimers from first-, second-, third- and fourth-generation pyridylimine-based poly(propylene) dendrimer scaffolds of the type, DAB-(NH2) (where n = 4, 8, 16 o ...
