Using Molecular Design to Influence Intermolecular Interactions
… describes the impact of molecular design on intermolecular interactions. Chapter 2 explores tuning the properties of contorted hexabenzocoronene (HBC) derivatives to improve photovoltaic performance. First, the interaction between contorted HBC derivatives with varying degrees of "bowl" …

Manganese-catalyzed intermolecular benzylic C–H amination
… C—H amination reactions are known, intermolecular C—H amination reactions with high reactivity and selectivity are scarce. Achieving high levels of reactivity while maintaining excellent site-selectivity and functional group tolerance remains an important challenge for intermolecular …

Tailoring Intermolecular Interactions for High-Performance Nanocomposites
Acid oxidation of multi-walled carbon nanotubes (MWCNTs) introduced carboxylic acid sites onto the MWCNT surface, which permitted further functionalization. Derivatization of carboxylic acid sites yielded amide-amine and amide-urea functionalized MWCNTs from oxidized precursors. Conventional MWCNT …

Determination of Noncovalent Intermolecular Interaction Energy from Electron Densities
<p>Noncovalent intermolecular interactions, widely found in molecular clusters and bio-molecules, play a key role in many important processes, such as phase changes, folding of proteins and molecular recognition. However, accurate calculation of interaction energies is a very difficult task because …

Intermolecular interactions in supercritical fluid solutions from fluorescence spectroscopy
Much of the unusual behavior in supercritical fluids (SCF's), including enhanced solubilities, synergistic effects of mixed solutes, and entrainer effects, may be explained by a region around the solute that has a higher density than the bulk. We present a new technique to investigae SCF's using …

Self-Assembly in Physisorbed Monolayers via Directional Intermolecular Interactions
In this work, the ability of two non-covalent directional interactions (halogen and hydrogen bonds) to influence the structure of self-assembled physisorbed organic monolayers is considered. These layers exhibit only weak, non-directional interactions with the substrate, and so their structure is …
