This book was released on 2015 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research project investigates the synthesis and spectroscopic analysis of organic and inorganic fluorescent and luminescent materials for future use in applications-based chemistry. This work specifically focuses upon fluorescent dyes with tunable emission properties designed for the investigation of applications less commonly explored in literature. The use of advanced spectroscopic and single particle fluorescence techniques is also an underlying theme of each chapter, used to elucidate the mechanism of emissive output from synthesised materials.Initial research focused upon the development water-soluble naphthalene diimides for use in biophysical applications (Chapter 3). Quenching ratios in water were first probed using steady state and time-resolved fluorescence techniques revealing that both static and dynamic quenching mechanisms play a role in visible fluorescence emission. Encapsulation of fluorescent naphthalene diimides into reverse and liposomal micelles (both used as biological membrane mimics) highlighted their potential for biophysical applications. It was shown using single particle techniques that the cavity size of dye loaded reverse micelles and diffusional parameters and hydrodynamic radii of dye loaded liposomal micelles could be accurately determined. Further research using naphthalene diimides led to the development of a series of supramolecular host-guest materials used to investigate non-bonding interactions (Chapter 4). Small naphthalene diimides were synthesised and the change in their photophysical properties probed upon incorporation into a cavity molecule, cucurbit[8]uril, which served as host. Results showed that the non-bonding interactions between naphthalene diimides and cucurbit[8]uril could be probed using numerous steady state and time-resolved fluorescence techniques, with the most interesting of the complexes forming an emissive 'excimer like' species with a fluorescence quantum yield of 7% in water, and a Stokes shift of more than 100 nm. Core-substituted naphthalene diimides were further developed as fluorescent sensing materials for small analytes such as protons as well as redox active compounds (Chapter 5). Two proton sensing naphthalene diimides and a series of redox sensing derivatives were synthesised and the mechanism of the sensing event spectroscopically probed using both steady state and time-resolved spectroscopic techniques. The mechanism of proton sensing was found to be photoinduced electron transfer from an electron donating tertiary nitrogen attached to the naphthalene diimide, which is subsequently suppressed upon protonation leading to an increase in emission. The emission output from one of the proton sensing materials was also found to be highly dependent upon solvent polarity and time-resolved methods were used to elucidate that the closeness in energy between the singly excited and the charge separated state leads to delayed fluorescence. Redox sensitive naphthalene diimides were analysed using steady state, cyclic voltammetry and computational modeling revealing the presence of highly conjugated small molecule systems that absorb and emit in the red/deep red region of the electromagnetic spectrum. This emission was modulated by the addition of oxidants and reductants and switched the fluorescence output 'on' and 'off' many times.Studies at the single molecule level were also completed using CdSe quantum nanocrystals (Chapter 6). Taking advantage of the inherent photostability of these semiconducting materials, the emission dipoles of quantum nanocrystals of different sizes and shapes were probed using defocused wide-field microscopy. Comparison of emission patterns to theoretically determined patterns showed that unlike CdSe spheres, which have a no discreet emission dipole, CdSe rods contain a single dipole moment down the c-axis of the crystal. This discreet dipole emission however, appeared to breakdown in rods with very small aspect ratios behaving more like spheres again.

Available in PDF, EPUB and Kindle. Book excerpt: The Who's Who in Fluorescence 2003 volume was published in November 2002. It featured some 312 personal entries from fluorescence workers all over the world. Initially we were unsure how useful the volume would be. However, it wasn't very long before we were inundated with requests for both bulk and personal orders. In addition a significant number of copies were freely distributed at conference venues, such as at the Biophysical Society meeting in San Antonio. Texas, March 2003, and at the Methods and Applications of Fluorescence Spectroscopy conference (MAFS) in Prague, Czech Republic, August 2003, where these two venues probably host the largest gathering of Fluorescence workers anywhere. Even when we were initially taking e-mail based submissions, contributors were freely commenting on what a useful resource they saw the volume as being. We subsequently shared these comments on the back outside cover of the 2003 volume. As well as individual scientists supporting the 2003 volume, the Fluorescence based Companies also played a key role, where without their financial support, the volume probably would not have the impact it currently has. As such, the Who's Who in Fluorescence 2003 has been a much bigger success than we ever envisaged. Subsequently, we now present the Who's Who in Fluorescence 2004 volume. The new volume features 359 personal entries from 35 countries around the world. In addition we have increased company support, which should enable us to distribute more copies at targeted venues in 2004.

Download or read book Fluorescent Dye Labels and Stains written by Tarso B. Ledur Kist and published by John Wiley & Sons. This book was released on 2023-03-10 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescent Dye Labels and Stains The only comprehensive database of fluorophores and their physical and photochemical properties Fluorophores are chemical compounds that strongly absorb in the ultraviolet, visible, and/or near-infrared and with bright emission in these ranges. As a result, they are exceptionally valuable as dyes for various analytical processes, capable of labelling and staining particular targets for purposes of fluorescent imaging, sensitive detection, and quantification (exhibiting linear responses over very wide concentration ranges). These compounds are many and varied, and panoramic views of their options, physical properties and their reactions to light excitations can be critical to their successful integration into chemical analysis, pharmaceutical analysis, clinical analysis, microscopies, optical bioimaging, cancer imaging, real-time PCR, flow cytometry, multiplexing in proteomics, life sciences in general, and many other high-tech fields (material sciences, traceability, photovoltaics, quantum computing). Fluorescent Dye Labels and Stains incorporates a comprehensive database of such substances and their characteristics. It provides an introduction to basic theories and foundational terminology, in addition to both the molecular structures and photophysical properties of an enormous range of fluorophores. Assembled over the course of a distinguished career in biochemistry, this database presents valuable information that has never before been available in a single volume. Readers will also find: Molecular and photochemical information of over 700 fluorophores A database of parameters, including light excitation ranges, molar absorption coefficients, fluorescence quantum yields, molecular brightness, and many more Information derived from multiple disciplines, including microscopy, nanoscopy, biochemistry, and molecular biology Fluorescent Dye Labels and Stains is the essential reference for pharmaceutical and biomedical researchers and professionals, academics who study molecular biology or organic chemistry, and any professional whose work includes strong and photostable molecular absorptions and fluorescence.

Download or read book Analytical Chemistry of Synthetic Colorants written by A.T. Peters and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than one and a half decades have passed since the last book was published describing developments in the analytical chemistry of synthetic colorants. In the intervening period, the scope and technical capabilities of instrumentation for analysing dyes and pigments has significantly expanded. It is now possible to rapidly resolve a number of problems whose solutions were previously either unattainable or very difficult to achieve. For instance, the unambiguous assignment of all the signals in the proton NMR spectrum of a trisazo direct dye, and the confirmation of the molecular weight of involatile, and, in particular, sulphonated dyes, without derivatisation, are now routine analytical techniques in many laboratories today. In addition, it is now possible to record the NMR spectrum of a dye molecule on less than 1 mg of material, and we are no longer limited to solution spectra, since solid samples can now be routinely analysed in NMR experiments. Whilst not attempting to be all encompassing, this volume is intended to bridge the gap between what was covered in the earlier work edited by Professor Venkataraman and the developments which have since ensued in some key areas. It provides important updates in X-ray crystallography, proton NMR, IR spectroscopy and mass spectrometry, and additionally covers topics such as ESR, micro spectrophotometry and emission spectroscopy.
