Palladium-based coordination cages as dynamic crosslinks in acrylamide hydrogels

Kay Severin, Sylvain Alexandre Marie Sudan, Damien Wen Chen, 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 ...

Selective Recognition and Extraction of Short‐Chain Perfluoroalkyl Carboxylates by a Supramolecular Receptor

Kay Severin, Farzaneh Fadaei Tirani, Damien Wen Chen

A supramolecular receptor for short‐chain perfluoroalkyl carboxylates was developed. The receptor displays a cage‐like geometry, with a defined binding site for the carboxylate head groups and an opening for the perfluoroalkyl side chains. The anionic gues ...

Two-Electron Redox Reactivity of Thorium Supported by Redox-Active Tripodal Frameworks

Rosario Scopelliti, Marinella Mazzanti, Damien Wen Chen, Fang-Che Hsueh

The high stability of the + IVoxidation state limits thorium redox reactivity. Here we report the synthesis and the redox reactivity of two Th(IV) complexes supported by the arene-tethered tris(siloxide) tripodal ligands [(KOSiR2Ar)3-arene)]. The two-elect ...

Orientational Self-Sorting in Octahedral Palladium Cages: Scope and Limitations of the “cis Rule”

Kay Severin, Farzaneh Fadaei Tirani, Atena-Bianca Solea, Damien Wen Chen, Jean Charles Edouard de Montmollin

Octahedral coordination cages of the general formula Pd6L1212 were obtained by combining Pd(CH3CN)42 with heteroditopic N-donor ligands. Four different ligands were employed. These ligands have 3-pyridyl donor groups at one end and 4-pyridyl, ...

Metal‐Mediated Synthesis of a Mixed Arduengo‐Fischer Carbodicarbene Ligand

Kay Severin, Farzaneh Fadaei Tirani, Damien Wen Chen, Bastiaan Kooij

Carbodicarbenes are strong C‐donor ligands, which have found numerous applications in organometallic and main group element chemistry. Herein, we report a structurally distinct carbodicarbene ligand, which is formed by dinitrogenative coupling of a Fischer ...

Synthetic Receptors with Micromolar Affinity for Chloride in Water

Kay Severin, Sylvain Alexandre Marie Sudan, Farzaneh Fadaei Tirani, Damien Wen Chen, Cesare Berton

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 ...
