Download or read book An Investigation of Naphthalenediimides as Central Building Blocks in Model Compounds for Scanning Tunneling Microscope Induced Light Emission Experiments and F rster Resonance Energy Transfer Studies written by Sandro Gabutti and published by Cuvillier Verlag. This book was released on 2010-03-19 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scanning tunnelling microscopy (STM) is a powerful technique to observe surfaces at the atomic level. The resolution of this STM technique is good enough to study the electronic properties of single molecules adsorbed onto metallic substrates. An important step towards controllable single molecular technologies is the determination of how the molecule-substrate interaction changes the local molecular electronic structure. Since this electronic structure of molecules is strongly perturbed by the electrons of the underlying metallic substrate, an electronic decoupling of the molecules from the metal surface is required to isolate the electronic properties of an individual molecule. Förster resonance energy transfer (FRET) has found many applications in different fields of science, because it allows the determination of the distance between two chromophores in the 1-10 nm range. In addition to other factors, this energy transfer is also dependent on the relative orientation of donor and acceptor chromophores to each other. This thesis describes the design, synthesis and investigations of model compounds for: 1). STM induced light emission experiments from single molecules and 2). for FRET studies. Chapter 1 provides an introduction to cyclophanes, energy transfer and scanning tunnelling microscopy. Chapter 2 gives a description of the aims of this work, which is split into the synthesis of cyclophanes for STM induced luminescence investigations and FRET studies. The later is complemented by the synthesis of a linear NDI system. Chapter 3 describes the design, synthesis and characterisation of all model compounds. In the first half STM investigations are presented and the electronic structure of two cyclophanes and complexation studies of the crown ether model compound are discussed. In the second half a modular synthetic route to asymmetric N,N’-naphthalenediimides is presented for FRET studies. Chapter 4 gives a summary of this thesis and presents a short outlook. Chapter 5 provides the synthesis and characterisation of all the compounds listed in this thesis and experimental details for STM investigations.

Download or read book DNA Conjugates and Sensors written by Keith R Fox and published by Royal Society of Chemistry. This book was released on 2012-11-30 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of nucleic acids have developed recently to provide solutions for biosensors, diagnostic tools and as platforms for the assembly of complex structures. These developments have been possible as their base sequence can be used to assemble precise structures following simple and predictable rules. Self-assembled DNA can then be amplified using polymerase chain reaction (PCR) and this ultimately enables the preparation of synthetic nucleic acids. Their use as molecular tools or DNA-conjugates has recently been enhanced by the addition of other groups including enzymes, fluorophores and small molecules. Written by leaders in the field, this volume describes the preparation and application of these DNA-conjugates. Several have been used as sensors (aptamers, riboswitches and nanostructures) based on the ability of nucleic acids to adopt specific structures in the presence of ligands, whilst others link reporter groups such as proteins or fluorophores to RNA or DNA for detection, single molecule studies, and increasing the sensitivity of PCR. The book is relevant to researchers in areas related to analytical chemistry, chemical biology, medicinal chemistry, molecular pharmacology, and structural and molecular biology.
