Palladium-based coordination cages as dynamic crosslinks in acrylamide hydrogels

Kay Severin, Damien Wen Chen, Sylvain Alexandre Marie Sudan, Chaolei Hu

Soft polymer networks with palladium cages as crosslinks can be obtained by combining polymeric N-donor ligands with PdII salts in organic solvents. Herein, we describe an alternative procedure that enables the preparation of hydrogels with PdnL2n-type jun ...

Palladium-based supramolecular assemblies: from complex structures to water-soluble anion-receptors

Sylvain Alexandre Marie Sudan

The combination of palladium salts and bipyridyl ligands can lead to the formation of a large variety of coordination complexes, with different shapes and sizes, displaying a very versatile host-guest chemistry. Increasing their structural complexity remai ...

Synthetic 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 ...

A 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 ...

LiBF4‐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 ...

Identification of a Heteroleptic Pd6L6L′6 Coordination Cage by Screening of a Virtual Combinatorial Library

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, Suzanne Maria Jansze, Rujin Li, Sylvain Alexandre Marie Sudan

The design of structurally defined heteroleptic coordination cages is a challenging task, and only few examples are known to date. Here we describe a selection approach that allowed the identification of a novel hexanuclear Pd cage containing two types of ...

Sustainable Capture of Aromatic Volatile Organic Compounds by a Pyrene-Based Metal-Organic Framework under Humid Conditions

Kyriakos Stylianou, Andrzej Gladysiak, Bardiya Valizadeh, Sylvain Alexandre Marie Sudan

The threat posed by the presence of artificial volatile organic compounds (VOCs) in the environment is a widely acknowledged fact, both for environmental issues and human health concerns. Ever-increasing production requires the continuous development of te ...
