Investigations 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 ...
EPFL2024Long live(d) CsPbBr3 superlattices: colloidal atomic layer deposition for structural stability
Raffaella Buonsanti, Philippe Benjamin Green, Alexander Nicolas Chen, Victoria Lapointe
Superlattice formation afforded by metal halide perovskite nanocrystals has been a phenomenon of interest due to the high structural order induced in these self-assemblies, an order that is influenced by the surface chemistry and particle morphology of the ...
Cambridge2024The 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 ...
2023Fast parametric analysis of trimmed multi-patch isogeometric Kirchhoff-Love shells using a local reduced basis method
Annalisa Buffa, Pablo Antolin Sanchez, Margarita Chasapi
This contribution presents a model order reduction framework for real-time efficient solution of trimmed, multi-patch isogeometric Kirchhoff-Love shells. In several scenarios, such as design and shape optimization, multiple simulations need to be performed ...
2023A multi scale consolidation model for press moulding of hybrid textiles into complex geometries
Side-by-side hybrid textiles are an intermediate step for the production of fibre-reinforcedthermoplastic composites. Press moulding these materials combining reinforcing fibre textiles andthermoplastic matrix textiles or flexible layers is a promising met ...
EPFL2023Can dd excitations mediate pairing?
Christophe Berthod, Francesco Barantani
The Cu-3d states in the high-T-c cuprates are often described as a single band of 3d(x2-y2) states, with the other four 3d states having about 2 to 3 eV higher energy due to the lower-than-octahedral crystal field at the copper sites. However, excitations ...
Amsterdam2023A Route to Stabilize Uranium(II) and Uranium(I) Synthons in Multimetallic Complexes
Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic
Herein, we report the redox reactivity of a multimetallic uranium complex supported by triphenylsiloxide (−OSiPh3) ligands, where we show that low valent synthons can be stabilized via an unprecedented mechanism involving intramolecular ligand migration. T ...
2023Mechanistic 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 SOC2022Competing Effects of Hydration and Cation Complexation in Single-Chain Alginate
Alginic acid, a naturally occurring anionic polyelectrolyte, forms strong physically cross-linked hydrogels in the presence of metal cations. The latter engage in electrostatic interactions that compete with intra- and intermolecular hydrogen bonds, determ ...
