Self-Assembly of Arylboronate Esters with Pyridyl Side Chains

Rosario Scopelliti, Kay Severin, Erin Sheepwash, Kai Zhou

Boronate esters that contain N-donor groups are self-complementary structures, which can assemble by means of dative boron–nitrogen bonds to form macrocycles or polymers. Herein, we describe the synthesis of dioxaborinanes and benzodioxaboroles containing ...

Precise Control of Intramolecular Charge-Transport: The Interplay of Distance and Conformational Effects

Jacques-Edouard Moser, Mateusz Barnaba Wielopolski, Lars-Hendrik Mewes

A new series of donor–bridge–acceptor (D–B–A) compounds consisting of π-conjugated oligofluorene (oFL) bridges between a ferrocene (Fc) electron-donor and a fullerene (C60) electron-acceptor have been synthesized. In addition to varying the length of the b ...

Syllable-based Pitch Encoding for Low Bit Rate Speech Coding with Recognition/Synthesis Architecture

Philip Neil Garner, Milos Cernak

Current HMM-based low bit rate speech coding systems work with phonetic vocoders. Pitch contour coding (on frame or phoneme level) is usually fairly orthogonal to other speech coding parameters. We make an assumption in our work that the speech signal cont ...

Multicomponent Assembly of Boronic Acid-Based Macrocycles, Cages, and Polymers

Burçak Içli

This work describes the synthesis and characterization of boronic acid-based supramolecular structures. Different reversible interactions such as boronate ester formation, imine condensation and dative B–N bond formation are used to assemble macrocycles, c ...

Multicomponent Assembly of Macrocycles and Polymers by Coordination of Pyridyl Ligands to 1,4-Bis(benzodioxaborole)benzene

Rosario Scopelliti, Kay Severin, Euro Solari, Burçak Içli, Benan Kilbas

Multicomponent reactions between 1,4-benzenediboronic acid, catechol, and different pyridyl ligands are reported. The condensation of 1,4-benzenediboronic acid with catechol gives 1,4-bis(benzodioxaborole)benzene. Upon crystallization, the ester aggregates ...

Bicyclization and tethering to albumin yields long-acting Peptide antagonists

Christian Heinis, Alessandro Angelini, Shiyu Chen, Philippe Diderich, Julia Morales Sanfrutos

Proteolytically stable peptide architectures are required for the development of long-acting peptide therapeutics. In this work, we found that a phage-selected bicyclic peptide antagonist exhibits an unusually high stability in vivo and subsequently deciph ...

Enantiopure, monodisperse alleno-acetylenic oligomers and cyclooligomers

Pablo Rivera Fuentes

Tert-butyl-substituted diethynylallenes (DEAs) are ideal for the construction of novel topologies because undesirable reactions on the cumulenic moiety are suppressed. The authors developed the asym. synthesis of two shape-persistent enantiopure alleno-ace ...

Controlling the formation of metallosupramolecular assemblies by metal ionic radii

The formation of either dinuclear double-stranded or pentanuclear circular helicates from a ligand containing two tridentate domains separated by a phenylene unit can be controlled by inter-ligand steric interactions which themselves are governed by the si ...

Combining Metallasupramolecular Chemistry with Dynamic Covalent Chemistry: Synthesis of Large Molecular Cages

Rosario Scopelliti, Kay Severin, Anton Granzhan

Ru-built cube: By combining metallasupramolecular chemistry with dynamic covalent chemistry, complex nanostructures can be formed. Large cages are synthesized by reaction of trinuclear metallamacrocycles containing pendant aldehyde groups. ...

DNA Topology

Guillaume Witz

This thesis explores different aspects of DNA topology through experimental and numerical techniques. Topology is a vast mathematical field, that deals with the spatial properties of objects undergoing continuous deformations, but here it is restricted to ...
