Ligand Effects in Low-Valent Co(I) Clathrochelate Complexes

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, Ophélie Marie Planes

Clathrochelate complexes of cobalt are known in the oxidation states I, II, and III. Low-valent Co(I) complexes are highly reactive compounds, and there is only limited knowledge about their structures in the solid state. Herein, we describe the crystallog ...

Syntheses and Applications of Boronate Ester-Capped Clathrochelate Complexes

Ophélie Marie Planes

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, ...

Incorporation of Clathrochelate-Based Metalloligands in Metal-Organic Frameworks by Solvent-Assisted Ligand Exchange

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, José Luis Bila, Ophélie Marie Planes, Pascal Alexander Schouwink

Iron(II) cage complexes with terminal 4-pyridyl groups can be incorporated in metal-organic frameworks (MOFs) via solvent-assisted ligand exchange (SALE). Paddle -wheeled MOFs with N,N'-di-4-pyridylnaphthalenete-tracarboxydiimide pillars were used as start ...

Two-Step Synthesis of Linear and Bent Dicarboxylic Acid Metalloligands with Lengths of up to 3 nm

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, Suzanne Maria Jansze, Ophélie Marie Planes

Nanometer-sized polycarboxylate ligands are interesting building blocks for metallasupramolecular chemistry, but access to these compounds is often limited by complicated synthetic pathways. Here, we describe a simple two-step protocol, which allows prepar ...

Cages vs. Prisms: Controlling the Formation of Metallosupramolecular Architectures with Ligand Side-Chains

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, Giacomo Cecot, Andrea Luca Ramorini, Ophélie Marie Planes, Martin Tim Doll

Metallosupramolecular assemblies of the general formula M2nLn can adopt prismatic or cage‐like structures. The factors controlling the aggregation number n and the geometry of the final assembly are still not fully understood. Here, we describe the synthes ...

Synthesis of Organic Super-Electron-Donors by Reaction of Nitrous Oxide with N-Heterocyclic Olefins

Andrzej Sienkiewicz, Kay Severin, Rosario Scopelliti, Basile Curchod, Léonard Yannick Maurice Eymann, Farzaneh Fadaei Tirani, Yizhu Liu, Ophélie Marie Planes, Paul Varava, Andrei Shved

The reaction of nitrous oxide (N2O) with N-heterocyclic olefins (NHOs) results in cleavage of the N–O bond and formation of azo-bridged NHO dimers. The latter represent very electron-rich compounds with a low ionization energy. Cyclic voltammetry studies s ...

Photocatalytic Hydrogen Generation from a Visible-Light-Responsive Metal–Organic Framework System: Stability versus Activity of Molybdenum Sulfide Cocatalysts

Berend Smit, Andreas Züttel, Kyriakos Stylianou, Daniele Ongari, Ophélie Marie Planes, Bardiya Valizadeh, Stavroula Kampouri, Wen Luo, Ngoc Tú Nguyên

We report the use of two earth abundant molybdenum sulfide-based cocatalysts, Mo(3)S(13)(2-)clusters and 1T-MoS2 nanoparticles (NPs), in combination with the visible-light active metal-organic framework (MOF) MIL-125-NH2 for the photocatalytic generation o ...
