Photochromic Torsional Switch (PTS): a Light-Driven Actuator for the Dynamic Tuning of π-Conjugation Extension

Pascal Miéville, Riccardo Petraglia, Emilie Baudat, Giuseppe Sforazzini, Adrien Georges Nicolai, Adam Antoni Sobczuk, Luca Cervini

Here we present a molecular architecture that can reversibly change the geometric conformation of its π-system backbone via irradiation with two different wavelengths. The proposed ‘molecular actuator’ consists of a photoswitchable azobenzene orthogonally ...

Recent progress in acentric core structures for highly efficient nonlinear optical crystals and their supramolecular interactions and terahertz applications

Christoph Peter Hauri

During the past decade, various new types of organic nonlinear optical crystals have been developed to overcome the benchmark stilbazolium DAST (4-(4-(N, N-dimethylamino) styryl)-1-methylpyridinium 4-methylbenzenesulfonate) crystal. Here, we review the ace ...

Functionalized Dinuclear Clathrochelates as Supramolecular Building Blocks

Mathieu Jérémie Marmier

This thesis details the synthesis and characterization of dinuclear clathrochelates functionalized with groups suitable for supramolecular applications. Their successful incorporation into self-assembled discrete and polymeric structures is related. These ...

Functionalised Clathrochelate Complexes – New Building Blocks for Supramolecular Structures

Kay Severin, Matthew David Wise

Tris(dioxime) iron(II) clathrochelate complexes functionalised with 3- and 4-pyridyl groups have been employed as building blocks in the preparation of supramolecular structures by coordination-driven self-assembly. These complexes possess a number of desi ...

Facile synthesis of oligoyne amphiphiles and their rotaxanes

Holger Frauenrath, Stephen Schrettl, Tobias Hoheisel, Ruth Szilluweit, Martin Fritzsche, Emmanuel Romaric Contal

Carbon-rich organic compounds containing a series of conjugated triple bonds (oligoynes) are relevant synthetic targets, but an improved access to oligoynes bearing functional groups would be desirable. Here, we report the straightforward synthesis of two ...

Functionalised clathrochelate complexes as supramolecular building blocks

Matthew David Wise

The work presented in this thesis entails the synthesis and characterisation of new iron(II) tris(dioxime) clathrochelate complexes functionalised with apical capping groups suitable for supramolecular applications, and their subsequent incorporation into ...

Triphenyltin(IV) adducts of diphosphoryl ligands: structural, electronic and energy aspects from X-ray crystallography and theoretical calculations

Kurt Schenk

Some triphenyltin(IV) adducts with a family of diphosphoryl ligands, RR'P(O)-X-P(O)RR' (R = OPh, Ph, R' = R, An (aniline)) and X = 1,4-OC6H4O, 1,4-OC6H4NH, 1,4-NHC6H4NH 1,4-(NHCH2)(2)C6H4, 1,3-(NHCH2)(2)C6H4 and piperazine have been synthesized and charact ...

The Caenorhabditis elegans protein SAS-5 forms large oligomeric assemblies critical for centriole formation

Pierre Gönczy, Georgios Hatzopoulos, Nicola Jane Dynes, Sheng Kai Pong

Centrioles are microtubule-based organelles crucial for cell division, sensing and motility. In Caenorhabditis elegans, the onset of centriole formation requires notably the proteins SAS-5 and SAS-6, which have functional equivalents across eukaryotic evol ...

The centriolar protein CPAP G-box: an amyloid fibril in a single domain

Georgios Hatzopoulos

Centrioles are evolutionarily conserved cylindrical cell organelleswith characteristic radial symmetry. Despite their considerable size (400 nm x 200 nm, in humans), genetic studies suggest that relatively few protein components are involved in their assem ...

Self-Assembly of a Giant Molecular Solomon Link from 30 Subcomponents

Rosario Scopelliti, Kay Severin, Yury Tsybin, Konstantin Nagornov, Konstantin Zhurov, Clément Schouwey

The synthesis of topologically complex structures, such as links and knots, is one of the current challenges in supramolecular chemistry. The so-called Solomon link consists of two doubly interlocked rings. Despite being a rather simple link from a topolog ...
