Enhanced Room-Temperature Photoluminescence Quantum Yield in Morphology Controlled J-Aggregates

Frank Nüesch, Jakob Heier, Surendra Babu Anantharaman

Supramolecular assemblies from organic dyes forming J-aggregates are known to exhibit narrowband photoluminescence with full-width at half maximum of approximate to 9 nm (260 cm(-1)). Applications of these high color purity emitters, however, are hampered ...

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, ...

Computational Analysis and Design of Structurally Stable Assemblies with Rigid Parts

Ziqi Wang

An assembly refers to a collection of parts joined together to achieve a specific form and/or functionality. Assemblies make it possible to fabricate large and complex objects with several small and simple parts. Such parts can be assembled and disassemble ...

New Methods for the Integrative Dynamic Modeling of Biomolecular Structures

Sylvain Träger

The true understanding of most cellular functions is only really achievable through the structural determination of their underlying macromolecular assemblies. However, their size, large number of individual components and metastable states make their eluc ...

Aggregation of discoidal particles due to depletion interaction

Ignacio Pagonabarraga Mora

Depletion interactions between colloids of discoidal shape can induce their self-assembly into columnar aggregates. This is an effect of entropic origin with important implications in a range of colloidal systems, particularly in the clustering of erythroc ...

Coordination-Driven Monolayer-to-Bilayer Transition in Two-Dimensional Metal–Organic Networks

Henning Paul-Julius Stahlberg, Mina Moradi

We report on monolayer-to-bilayer transitions in 2D metal–organic networks (MONs) from amphiphiles supported at the water–air interface. Functionalized calix[4]arenes are assembled through the coordination of selected transition metal ions to yield monomol ...

Boronate Ester-Capped Helicates

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Daniel Ortiz Trujillo, Erica Giraldi

Triple‐stranded helicates were obtained by metal‐templated multicomponent reactions of bispyridyloxime ligands with arylboronic acids. The helicates feature two hexa‐coordinated MII ions (M=Fe, Zn, or Mn), which are embedded in a macrobicyclic ligand frame ...

Soft matter probed by nonlinear scattering: self-assembly, interfaces, hydration, and long-range order

Jan Dedic

All organisms are made to a large extent of soft matter - macromolecules such as proteins and polysaccharides, or assemblies of small molecules such as lipids embedded in an aqueous environment. Understanding the role of order in soft matter presents a cha ...

Long-Range Exciton Diffusion in Two-Dimensional Assemblies of Cesium Lead Bromide Perovskite Nanocrystals

Raffaella Buonsanti, Anna Loiudice

Forster resonant energy transfer (FRET)-mediated exciton diffusion through artificial nanoscale building block assemblies could be used as an optoelectronic design element to transport energy. However, so far, nanocrystal (NC) systems supported only diffus ...

The role of xanthophylls in the supramolecular organization of the photosynthetic complex LHCII in lipid membranes studied by high-resolution imaging and nanospectroscopy

Giovanni Dietler, Serguei Sekatski, Jiangtao Zhou

The xanthophyll cycle is a regulatory mechanism operating in the photosynthetic apparatus of plants. It consists of the conversion of the xanthophyll pigment violaxanthin to zeaxanthin, and vice versa, in response to light intensity. According to the curre ...

Electrochemical Assay for Extremely Selective Recognition of Fructose Based on 4-Ferrocene-Phenylboronic Acid Probe and beta-Cyclodextrins Supramolecular Complex

Sandro Carrara, Irene Taurino

The aim of the present paper is to highlight a novel electrochemical assay for an extremely-selective detection of fructose thanks to the use of a supramolecular complex between beta-cyclodextrins (beta-CDs) and a chemically modified ferrocene with boronic ...
