Nanogels with Metal‐Organic Cages as Functional Crosslinks
A dinuclear metal-organic cage with four acrylate side chains was prepared by self-assembly. Precipitation polymerization of the cage with N-isopropylacrylamide yielded a thermoresponsive nanogel. The host properties of the cage were retained within the ge ...
2024Molecular imine cages with π-basic Au3(pyrazolate) faces
Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Noga Eren
One tetrahedral and two trigonal prismatic cages with π-basic Au3(pyrazolate)3 faces were obtained by connection of pre-formed gold complexes via dynamic covalent imine chemistry. The parallel arrangement of the Au3(pyrazolate)3 complexes in the prismatic ...
2024Synthetic Receptors with Micromolar Affinity for Chloride in Water
Kay Severin, Farzaneh Fadaei Tirani, Damien Wen Chen, Cesare Berton, Sylvain Alexandre Marie Sudan
A water-soluble coordination cage was obtained by reaction of Pd(NO3)2 with a 1,3-di(pyridin-3-yl)benzene ligand featuring a short PEG chain. The cavity of the metal-organic cage contains one nitrate anion, which is readily replaced by chloride. The appare ...
Wiley2023Grand canonical Brownian dynamics simulations of adsorption and self-assembly of SAS-6 rings on a surface
Pierre Gönczy, Niccolo Banterle
The Spindle Assembly Abnormal Protein 6 (SAS-6) forms dimers, which then self-assemble into rings that are critical for the nine-fold symmetry of the centriole organelle. It has recently been shown experimentally that the self-assembly of SAS-6 rings is st ...
AIP Publishing2023A Simple, Transition Metal Catalyst-Free Method for the Design of Complex Organic Building Blocks Used to Construct Porous Metal-Organic Frameworks
Wendy Lee Queen, Jordi Espin Marti, Jocelyn Richard Roth, Till Marian Schertenleib, Nazanin Taheri, Ilia Kochetygov, Anita Justin, Sophia Alessandra Pache
The design of metal-organic frameworks (MOFs) having large pore sizes and volumes often requires the use of complex organic ligands, currently synthesized using costly and time-consuming palladium-catalyzed coupling chemistry. Thus, in the present work, a ...
WILEY-V C H VERLAG GMBH2023A five-stranded heterometallic helicate
Kay Severin, Farzaneh Fadaei Tirani, Sylvain Alexandre Marie Sudan
A penta-stranded helicate was obtained by combining Pd(CH3CN)42 with La(NO3)3 and a polydentate ligand. The helicate displays low symmetry, both in solution and in the solid state. A dynamic interconversion between the penta-stranded helicate and a ...
2023LiBF4‐Induced Rearrangement and Desymmetrization of a Palladium‐Ligand Assembly
Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Sylvain Alexandre Marie Sudan
Thirteen palladium-ligand assemblies with different structures and topologies were investigated for the ability to bind lithium ions. In one case, the addition of LiBF4 resulted in a profound structural rearrangement, converting a dincluclear [Pd2L4]2 comp ...
2022Half-clathrochelate Complexes as Versatile Links in Supramolecular Chemistry
Clathrochelate complexes have been widely investigated with different size and shape and used as building blocks for the obtainment of discrete supramolecular architectures. These clathrochelate complexes are very stable and kinetically inert complexes. A ...
EPFL2021Luminescent, porous, metal-organic crystals: Design, synthesis, and applications
The work presented in this thesis is focused on the design and discovery of new luminescent, porous, crystalline materials for targeted applications. In particular, we focus on luminescent Metal-Organic Frameworks (MOFs) and Organic Molecules of Intrinsic ...
EPFL2021Syntheses and Applications of Boronate Ester-Capped Clathrochelate Complexes
This thesis describes the syntheses of novel boronate ester-capped clathrochelate complexes and their application in supramolecular chemistry, materials science, and chemical biology.
Chapter 2 shows the synthesis of long Fe(II) dinuclear clathrochelates, ...
