Abstract

When molecules transition from solution into the condensed phase, their behavior and properties are to a large extent governed by intermolecular interactions.  Despite the fact that such chemical bonds are relatively weak and reversible they are critically important to solubility, thermal and mechanical stability, optical properties, and many other key performance parameters of modern materials.  Consequently, if we want to acquire the ability to design and construct new materials through a bottom-up approach that is both robust and versatile, we need a better understanding of the structural consequences, and balance between, intermolecular forces.  In addition, we also need to establish more reliable and tangible connections between molecular structure and materials properties.  In this presentation we will examine how several fundamental physical properties of a substance can be modified and ‘dialed-in’ through the use of co-crystallization technologies that are firmly anchored in a fundamental understanding of intermolecular forces.   Applications relevant to pharmaceutics, agrochemicals, and explosives will be presented.

Abstract: 
The use of hypervalent I(III) reagents for the oxidation of late transition metals is a topic of major interest. In particular the groups of Sanford and Ritter have used I(III) compounds such as PhICl2 and PhI(OAc)2 to access Pd(IV) complexes, which have been used mainly in stoichiometric and catalytic C-H activations. The Dutton group has been studying the use of dicationic I(III) complexes [PhI(pyridine)]2+ as  oxidants for late metals for chemistry involving Pd(IV), Pt(IV) and Au(III). Most significantly we have used this method to synthesize homoleptic Au(III) trications, which represent a new family of gold compounds. These Au(III) trications can be used to access unique reactivity between gold and water, as well as extremely rare examples of Au(III)-F complexes, generated using simple fluoride sources such as KF.

Title: “From Structure to Interactions to In vivo NMR: The vast potential of NMR Spectroscopy in Environmental Research”
Web: http://www.utsc.utoronto.ca/~asimpson/

Room #186 Essex Hall

Abstract:

NMR spectroscopy is arguably the most powerful tool for elucidating structures and probing molecular interactions. Practically all environmental research, at least to some extent, involves working with ultra-complex natural mixtures that are ubiquitous in soil, water, and air. NMR can provide information not only as to the basic chemical structures present in a mixture, but can potentially provide information as to the self-associations of molecules (aggregation and flocculation processes), their mechanistic interactions with xenobiotics (transport of contaminants) and provide the direct connection between molecular scale processes (environments of individual nuclei) and macroscopic scale (visual), in the form NMR imaging. 

This presentation will take the audience through an evolution of my career from molecular-structure at one extreme to the impact of chemicals in living systems at the other.

Structure: Understanding the structure of soils, air particles, and dissolved organic is a critical precursor to understanding how these materials function. This information is desperately needed to develop the most efficient soil remediation and agricultural practices as-well as better predict carbon sequestration and climate change.

Interactions: With a better understanding as to the structural components and NMR assignments for key environmental matrices it is then possible to determine, how, where, and why contaminants get sequestered and are challenging to remediate. A range of novel NMR experiments will be introduced along with a new technology termed comprehensive multi-phase NMR. Comprehensive Multiphase (CMP) NMR, was co-developed between my group and Bruker Biospin. The approach combines all the electronics from solution-state, semi-solid and solid-state NMR into a single NMR probe. The resulting technology permits an uncompromised analysis of liquid, semi-solid and solid components within unaltered samples in their natural swollen state. As well as unravelling the binding orientation, and receptors for contaminants/drugs CMP-NMR is also capable of monitoring the kinetic transfer between and across interfaces providing an unprecedented window into otherwise inaccessible molecular information.

Impact: With an understanding as to “what soil is?” and “which chemical components bind contaminants?" the key questions become “what does it all mean?” and “how are living systems impacted?”. For example, if a herbicide is bound tightly to the protein fraction of soil is it still bioavailable? Would this still hold true with climate change or change in land use? An even more challenging but important question is “out of the 100’s or 1000’s chemicals we are exposed to everyday which ones truly impacts our health?” Indeed similar questions are asked everyday by policy makers. NMR has great potential to address such challenges when employed as the “molecular interpreter” of living systems under environmental stress. In this final section in-vivo NMR is introduced on small invertebrates. Static studies (i.e. using a flow system and solution-state probes) provide a low stress environment to study metabolic flux in response to stressors. Conversely, CMP-NMR, can potentially be used to study and differentiate different phases (liquids (metabolites), gels (proteins, membranes), solids (shell, bone)) in-vivo. A wide range of novel experiments will be introduced that greatly improve the depth and breadth of information that can be obtained from NMR of living systems. Combined the approaches hold the potential to identify which are the most potent environmental stressors in complex natural samples, explain their toxic-mode-of-action and even act as early warning system to identify environmental stress, prior to disease, or ecosystem shifts.

Abstract:

In contemporary crystal engineering halogen bonding is booming due to its directionality, specificity and high strength allowing preparation of highly complex structures with a high degree of accuracy and precision.1-3 Surprisingly, yet being the most difficult to achieve, hollow molecular assemblies solely based on halogen bonding have only very recently been achieved. Our group4 and Francois Diederich5 (ETH, Zürich) both published, in 2015 and nearly simultaneously, the first molecular capsules solely based on halogen bonds. Even though halogen bonding is more directional than hydrogen bonding it is even more sensitive to the environment and has thus mostly been demonstrated in the solid-state. Studies on halogen bond donor cavitands6 and collaboration with Mate Erdelyi (University of Gothenburg, Sweden, at present Uppsala University) on halonium ion based halogen-bonded complexes7 based on [N···Ag+···N] to [N···I+···N] cation exchange reaction inspired us to exploit halonium ions as very robust halogen bond donors. The first supramolecular, halonium ion mediated, dimeric capsule8 is based on a resorcinarene-based, conformationally fixed cavitand that is functionalized with four adjacent meta-pyridyl units acting as the XB acceptors. Assembly of the two cavitands first with silver(I) cations followed by a subsequent reaction of the dimeric silver capsule with molecular iodine leads to [N···I+···N] halogen-bonded dimeric capsule through [N···Ag+···N] to [N···I+···N] cation exchange reaction.8 Most recently we have managed to create an extremely robust large, even hexameric, halogen-bonded molecular capsules with the help of [N•••I+•••N] halogen bonds.9-10

Abstract:

In this seminar, I will discuss work in our group focusing on the development of cluster and nanoparticle catalysts which have high catalytic activity, excellent selectivity towards specific substrates, and excellent durability and recyclability. Our current work involves the synthesis and stabilization of clusters and nanoparticles in solution followed by activating them for catalysis. Several routes towards such goals will be discussed, including the activation of monolayer-protected Au clusters and structural control of bimetallic nanoparticles. Characterization tools which can assist in elucidating surface chemistry and/or cluster and nanoparticle sizes and structures will be detailed, including mass spectrometry, HRTEM, and in situ x-ray absorption spectroscopy at the Canadian Light Source.
