Carboxylic acid isomer-directed synthesis of CdS nanocluster isomers
Selective synthesis of nanocluster (NC) isomers with tailored structures holds significant importance for enhancing their applications. Here, we develop an effective strategy for the selective synthesis of CdS NC isomers through the judicious choice of a p ...
Royal Soc Chemistry2024Investigations about the Chemistry of Tetraarylethene- and Iridium-Based Luminophores
The work described in this thesis focuses on two classes of luminophores: tetraarylethene-based polymers and Ir(III) complexes with orthometalated ligands. Tetraarylethene-based polymers show aggregation-induced emission (AIE) and they are of interest for ...
EPFL2024The acid-mediated isomerization of iridium(iii) complexes with cyclometalated NHC ligands: kinetic vs. thermodynamic control
Kay Severin, Farzaneh Fadaei Tirani, Anastasia Gitlina
The isomerization of iridium(III) complexes with metalated N-heterocyclic carbene (NHC) ligands was studied. The fac isomers of complexes with 1-phenyl-3-methylbenzimidazolin-2-ylidene or 1-phenyl-3-benzylbenzimidazolin-2-ylidene ligands are transformed cl ...
2023Identification of N-glycan positional isomers by combining IMS and vibrational fingerprinting of structurally determinant CID fragments
Thomas Rizzo, Ahmed Ben Faleh, Stephan Warnke, Priyanka Bansal
While glycans are present on the surface of cells in all living organisms and play key roles in most biological processes, their isomeric complexity makes their structural characterization challenging. Of particular importance are positional isomers, for w ...
ROYAL SOC CHEMISTRY2022Acid-base-induced fac → mer isomerization of luminescent iridium(iii) complexes
Kay Severin, Farzaneh Fadaei Tirani, Albert Ruggi, Anastasia Gitlina, Carolina Luciana Plaice
Luminescent Ir(C^N)3 complexes (C^N = cyclometalated arylpyridine ligand) exist in the form of two stable isomers with distinct photophysical and electrochemical properties: fac and mer. Herein, we show that fac-Ir(C^N)3 complexes can be converted into the ...
2022Identification of Mobility-Resolved N-Glycan Isomers
Thomas Rizzo, Robert Paul Pellegrinelli, Ahmed Ben Faleh, Stephan Warnke, Priyanka Bansal
ABSTRACT: Glycan analysis has evolved considerably during the last decade. The advent of high-resolution ion-mobility spectrometry has enabled the separation of isomers with only the slightest of structural differences. However, the ability to separate suc ...
AMER CHEMICAL SOC2022Mechanistic Insight into Supramolecular Polymerization in Water Tunable by Molecular Geometry
Supramolecular self-assembly in water based on non-covalent bonding is attracting major attention due to the potential of hydrogels and aqueous polymers in biomedical applications. Although supramolecular polymerization in organic solvents is well establis ...
CHINESE CHEMICAL SOC2022Quantifying the Solution Structure of Metal Nanoclusters Using Small-Angle Neutron Scattering
Francesco Stellacci, Stefan Guldin, Ye Yang, Zhi Luo, Huayan Yang
Metal nanoclusters are a unique class of synthetic material, as their crystal structures can be resolved using X-ray diffraction, and their chemical formula can be precisely determinated from mass spectroscopy. However, a complete structure characterizatio ...
