Abstract:

Over the past ten years, the development of High Throughput (HT) synthetic chemistry techniques has allowed the rapid preparation of libraries of hundreds to thousands of compounds. These tools are now extensively used for drug and material discovery programmes. The subsequent development of analytical capabilities to carry out qualitative and quantitative assessment of the compounds generated by HT synthesis as well as their HT screening has led to a dramatic broadening of the scope of HT techniques, ranging from image based analysis techniques to mass spectrometry (MS). Based on the latter,

The optimized synthesis of acyclic dialkoxy disulfides and aromatic polysulfides is described and their physical properties probed. A theoretical survey of dialkoxy disulfides and thionosulfites was undertaken in order to determine the most efficacious method for accurately modeling these compounds. In particular, the origin of the high barrier to rotation in the dialkoxy disulfides was determined to be due to a generalized anomeric effect resulting from two lone pair donations of each sulfur atom into each of their respective sulfur-oxygen antibonding orbitals. The origin of the high r

Abstract:

<p> Energy generation via organic photovoltaic (OPV) cells provide many advantages over alternative processes including flexibility and price. However, more efficient OPVs are required in order to be competitive for applications. One way to enhance efficiency is through manipulation of exciton mechanisms within the OPV, for example by inserting a thin film of bathocuproine (BCP) and gold nanoparticles between the C<sub>60</sub>/Al and ZnPc/ITO interfaces, respectively. We find that BCP increases efficiencies by 330% due to gains of open circuit voltage (<i>V<sub>oc</sub></i>) by 160% and short

Proton transfer reactions to monosubstituted benzenes have been studied in the gas phase as a function of protonation exothermicity using tandem mass spectrometry.

It is shown that during the reaction of CHs<SUP>+</SUP> with fluorobenzene at temperatures less than 330K, proton transfer occurs preferentially to the F atom even though its proton affinity is approximately 180kJmol<SUP>-1</SUP> less than the ring.

Increasing the efficiency and durability of organic light-emitting diodes (OLEDs) has attracted attention recently due to their prospective wide-spread use as flat-panel displays. The performance and efficiency of OLEDs is understood to be critically dependent on the quality of the device heterojunctions, and on matching the ionization potentials (IP) and the electron affinities (EA) of the luminescent material (LM) with those of the hole (HTA) and electron (ETA) transport agents, respectively.

<p> Nuclear spin induced optical rotation (NSOR) is a novel technique for the detection of nuclear magnetic resonance (NMR) via optical rotation instead of conventional pick-up coil. Originating from hyperfine interactions between nuclei and orbital electrons, NSOR provides a new method to reveal nuclear chemical environments in different molecules. Previous experiments of NSOR detection have poor signal-to-noise ratio (SNR), which limits the application of NSOR in chemistry.

Crystallization of molecules is a well-known phenomenon and it plays an important role in various industrial domains, including pharmaceutical, yet it remains poorly understood.

We took the approach of surface templated crystallization in order to get an increased understanding of selective polymorph growth processes. Three main parameters were chosen for investigation: the type of interactions between molecules in solution and interfaces, SAM packing and the introduction of a step within the SAM.

Values for the melting points, total enthalpies of melting, and total entropies of melting of organic compounds are required in order to accurately estimate properties such as aqueous solubility and vapor pressure.

Despite their importance, relatively few methods are available for predicting these properties from chemical structure. One reason for the lack of available methods is that these properties are easily obtained experimentally. The major reason, however, is tha

Abstract:

The structure elucidation of gas-phase isomeric species $\rm C\sb2H\sb4X\sp+$ (X = F, Cl, Br and I), $\rm C\sb3H\sb6X\sp+$ (X = Cl, and Br), $\rm(C\sb2H\sb5)\sb2O\sp+C\sb2H\sb4X$ (X = Cl and Br), and $\rm C\sb3H\sb6O\sb2\sp{+\cdot}$ has been accomplished by employing tandem mass spectrometric techniques, i.e. metastable ion (MI) mass spectrometry, collision induced dissociation (CID) mass spectrometry, collision induced dissociative ionization (CIDI) mass spectrometry and neutralization reionization (NR) mass spectrometry. For $\rm C\sb2H\sb4X\sp+$ cations, apart from the $\alpha$-isomer, $\rm

Abstract:

Organized organic films form a new class of nanomaterials, having potential applications in biosensing and molecular electronics. The development of such devices is impeded by the lack of simple and reliable methods for depositing molecular assemblies. An original electrodeposition scheme that allows for the formation of functionalized organic monolayers has been developed. With this method, it is possible to create organic interfaces that can be made to selectively react through application of an electric field. This electrochemical approach has been used to form reproducible monolayers and b
