Departmental Seminar:
New Strategies for the Synthesis of Boronic Acid Derivatives

Abstract: Aromatic and heteroaromatic boronic acid derivatives are one of the most valuable classes of intermediates in synthetic chemistry. Their value lies in their unique combination of high stability and rich reactivity, allowing them to participate in a wide range of functionalisation reactions. This lecture will describe benzannulation reactions of simple fragments that contain a pre-existing boronic ester moiety, leading to new reaction pathways and high value products.

Dainton Building LT1

Speaker: Dr Helen Willcock
Loughborough University

Host: Dr Seb Spain

Departmental Seminar:
Synthesis of Polymer Particles, from Nanometre to Micron Sized

Abstract: Control over the architecture and functionality of polymers gives us exquisite control over their solution properties and can often be achieved using commercially available starting materials. By incorporating responsive groups, such as charged or zwitterionic monomers, the solution properties of the polymer can be finely tuned and controlled by application of an external stimulus, such as pH or temperature. However, the incorporation of responsive groups by their very nature introduces complexity and can cause problems during synthesis and application. Zwitterionic, or betaine polymers such as PDMAPS exhibit unique properties including anti-polyelectrolyte and low protein fouling behaviour, as well as biocompatibility.
Here, the synthesis of betaine polymers by both Reversible Addition Fragmentation chain Transfer (RAFT) polymerisation and dispersion and emulsion techniques will be discussed, demonstrating how the architecture and functionality of the polymer can affect both particle formation and the responsive behaviour of the polymer. Specifically, the first reported synthesis of micron-sized, discrete cross-linked polybetaine particles, using polymerisation in scCO2 with methanol as a co-solvent will be presented. The effect of crosslinking density, monomer loading, and reaction conditions will be discussed. A spherical morphology and extremely low size dispersity is observed by SEM analysis, and importantly the particles can be readily re-dispersed in aqueous solution and light scattering measurements confirm their monodisperse nature.
Current examples of the Willcock group research demonstrating the incorporation of functionality into polymeric scaffolds for various applications will also be highlighted.

Departmental Seminar:
Making the Tiniest Machines

Over the past two decades some of the first examples of synthetic molecular level machines and motors—albeit primitive by biological standards—have been developed. Perhaps the best way to appreciate the technological potential of controlled molecular-level motion is to recognise that nanomotors and molecular-level machines lie at the heart of every significant biological process. Over billions of years of evolution Nature has not repeatedly chosen this solution for achieving complex task performance without good reason. When we learn how to build artificial structures that can control and exploit molecular level motion, and interface their effects directly with other molecular-level substructures and the outside world, it will potentially impact on every aspect of functional molecule and materials design.

Departmental Seminar:
Liquid-microjet Photoelectron Spectroscopy of Biochromophores

Much of our detailed understanding of the intrinsic electronic relaxation dynamics of photoexcited molecules has come from gas-phase experiments and calculations involving isolated molecules, free from interactions with solvent or protein environments. However, electronically excited states are sensitive to their microenvironment, particularly in polar solvents such as water, the most important medium in chemistry and biology. Experimentally, photoelectron spectroscopy (PES) is an ideal tool for probing the electronic structure of molecules through the measurement of electron binding energies. This presentation will describe recent work from our group employing the emerging technique of liquid-microjet PES to unravel the electronic structure and relaxation dynamics of biologically important chromophores following photoexcitation in aqueous environments.

Departmental Seminar:
From molecular self-assembly to photocatalyst materials: insights from theory in partnership with experiment

Abstract: Theoretical chemistry is a powerful tool which allows us to gain insight into structures and properties of materials. In this talk, I will show how theoretical modelling works in partnership with experimental studies to elucidate the structures and identify structure-property relationships of materials. I will present examples from two areas of chemistry: molecular self-assembly in two dimensions (on surfaces and at solid/liquid interfaces), where our calculations revealed the nature of temperature-induced transformations in metal-coordinated superstructures on surfaces, and research on photocatalyst materials, where we used computational modelling to predict properties of new carbon nitride-based materials and to discover the reasons for the high photocatalytic efficiency of the recently synthesized oxygen-containing polymeric carbon nitride.

Departmental Seminar:
Identifying electron transfer pathways using projected modes.

Electron transfer between molecular donor and acceptor species is a fundamental mechanism for a wide range of chemical processes including photosynthesis, respiration, and detoxification. The cornerstone theory for this is from Marcus which gives the transfer rate between two redox centers in terms of the driving force, reorganization energy, and non-adiabatic coupling. Lost in this description is a clear indication of specific nuclear motions that accompany the process. In my talk, I shall discuss an approach we have developed using a search algorithm similar to that used by Netflix to find the optimal combinations of nuclear normal modes that drive and couple intramolecular electronic transitions. I shall discuss our theoretical advances in light of experiments by Prof Weinstein’s group in Sheffield that probe energy transfer in Pt bridged donor/acceptor complexes.

Computational Molecular Materials Discovery

We have been developing an evolutionary algorithm targeted upon the discovery of optimal structures and properties for molecular materials. Whilst initially we have focused upon porous molecular materials, we will also address the ways in which our approach is generalisable to other molecular materials and their applications, including as organic semiconductors or for photocatalysis. We will also explore the use of machine learning for the rapid prediction of materials properties.

Departmental Seminar:
Evolving Molecular Diversity

Abstract: Natural products (NPs) represent a hugely important source of pharmaceutical and agrochemical agents. For example, most of the antibiotics in clinical use are of natural origins and, remarkably, around half of these come from a single bacterial genus (Streptomyces). Despite these successes many NPs do not have the physical properties required to make them successful as a pharmaceutical agent without some structural modification, but their structural complexity makes this task difficult. To address this problem we developed an approach we term ‘biosynthetic medicinal chemistry’ where synthetic chemistry methods are augmented with biosynthetic engineering to enable the optimization of NP lead molecules. In my lecture I will provide some background to this area and provide examples of successes, and discuss limitations, from our work of the last two decades. I will finish with recent work in which we take inspiration from how nature evolves biosynthetic pathways.
