All substances consist of one or several molecules, which can exhibit a versatile range of properties. Two key aspects of chemical research are the synthesis of novel functional molecules and the development of an in-depth understanding of their molecular functionalities. Based on this idea, our research interest focuses on the design and synthesis of new functional molecules based on phthalocyanines and porphyrins as well as the elucidation of the origin of their molecular functionalities based on spectroscopic analyses and theoretical calculations.

Chemists possess an unparalleled understanding of how the complexity of macroscopic matter emerges from the relative simplicity of atoms and molecules; we seek to employ these insights to investigate the widening interface between chemistry, material science and biology. Our research program aims to develop tools to interrogate, understand and manipulate the interactions that occur between (bio)macromolecules. Synthetic chemistry and the development of new methods underpin all aspects of our research, and we apply the principles of chemistry towards the precise molecular-level design and engineering of these systems.

We are developing computational models to quantitatively describe the origins of reactivity and selectivity in organocatalytic and transition metal-catalyzed reactions. We perform quantum mechanical calculations to explore the reaction mechanism, followed by thorough analysis on various stereoelectronic effects to predict how changes of the catalyst structure, substituents, and solvent affect rate and selectivity. We use quantitative energy decomposition methods to dissect the key interactions in the transition state and provide chemically meaningful interpretation to the computed reactivity and selectivity. We apply these computational studies to a broad range of organic and organometallic reactions, such as C–H and C–C bond activations, olefin hydrofunctionalization, olefin metathesis, and polymerization reactions.

The O’Doherty research group has been developing new methods for the de novo synthesis of natural and unnatural structures, with a particular focus on the synthesis of biologically active natural products and carbohydrate motifs. Our overarching synthetic goal is to use asymmetric transition metal catalysis to create absolute stereochemistry and a combination of catalysis and substrate control for diastereocontrol. This concept can be seen in several of our natural product syntheses as well as our expanding ability to synthesize carbohydrates. For example our early efforts to control all the stereochemistry of monosaccharides led to using catalysis to control the stereochemistry of the glycosidic bond and ultimately complex oligosaccharides. A long-term theme to this research is the development of highly stereoselective transformation that can be used for not only synthesis but also to enable medicinal chemistry studies. In fact, we have already had great success along these lines

Organic small molecules make up the vast majority of medicines, biological probes, agrochemicals, and materials building blocks. Thus, though they are ubiquitous in modern society, many classes of small molecules remain problematic to prepare using conventional methods. Contemporary synthetic routes routinely require multiple steps, generate large quantities of waste, or require substantial human energy to troubleshoot. Research in the Engle group focuses on addressing these challenges by harnessing the power of catalysis. Our group’s goal is to advance the efficiency, effectiveness, and sustainability of chemical synthesis. The projects that we tackle are highly interdisciplinary, and as a consequence, students complement their core training in synthetic organic, physical organic, and organometallic chemistry with expertise in related disciplines in and outside of chemistry.

The discovery of catalysts is of great importance to the practice of modern synthetic chemistry, both to improve upon the existing catalog of chemical transformations and to generate new modes of reactivity. Research in the Malcolmson lab focuses on the discovery of novel methods for the efficient and selective synthesis of small molecule scaffolds through the design and development of new catalysts. In these transformations, we seek to realize new synthetic bond disconnections while also controlling some aspect of selectivity (e.g., enantio-, and/or site selectivity). The catalysts and methods developed in the group are being applied to the synthesis of biologically active molecules to drive the development of new chemistry as well as help to address problems in human health.

Biomimetic Chemistry: The most complex and elegant examples of "nanotechnology" come from Nature. In our group we first look to Nature for inspiration when it comes to solving the problems we are currently dealing with in nanotechnology (e.g., biosensors or tissue engineering). This is the philosophy of bio-mimetic chemistry, which underpins most of the work in our group.
Overview: At the core of nearly all of our work is the art of synthetic organic chemistry, however, we also apply techniques from across the whole spectrum of chemistry (physical, inorganic, organic, supramolecular and surface chemistry) as well as biochemistry, biophysics and biology. Methods (synthesis and/or self-assembly) to direct the assembly of functional molecules are of particular interest to us as are methods to analyse nanostructures, e.g. by the use of scanning probe microscopy (AFM and STM) and other advanced characterisation tools.

Our research is centred on the development of environmentally friendly techniques for the synthesis of functional polymeric materials. A major focus is photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerisation where we are continuing to develop novel photoredox catalysts.
We are also developing various polymerisation techniques for visible-light-cotrolled radical polymerisation, such as continous flow PET-RAFT polymerisation and high-throughput synthesis of polymers through photopolymerisation in open-air. Furthermore, we are exploring photopolymerisation in dispersed media for the synthesis of polymeric nanoparticles through polymerisiation-induced self assembly (photo-PISA). Another focus is adapting the aforementioned techniques to the fabrication of advanced polymeric materials for new synthetic antimicrobial macromolecules.

The Nagib Laboratory seeks to bridge the gap between what is possible and practical in the realm of organic synthesis. Our goal is to expand the synthetic toolbox by designing fundamentally new activation strategies and catalysts. We aim to harness the untapped reactivity of cheap and abundant chemical feedstocks as well as enable the late-stage functionalization of complex natural products. We are currently inventing multi-faceted approaches for selective C-H and C-O activation, using combinations of radical (1e-) and closed shell (2e-) processes. By emphasizing the design of novel, dual-catalytic strategies (organometallic, organocatalytic, redox-neutral, etc.) and a careful elucidation of their unique mechanisms, we are developing useful methodologies to enable non-classical synthetic disconnections. Our chemistry has important applications in various interdisciplinary arenas, including the streamlined synthesis of improved medicines, materials, and biofuels.

Despite the power of modern organic chemistry, efficient synthesis of complex molecular scaffolds remains an unmet challenge. Their intricate ring systems and stereochemical arrays require too many synthetic operations to rapidly produce libraries of analogs. New technological approaches are needed to forge their varied bonds to provide scalable access to libraries of these molecular architectures. Through detailed mechanistic study, such technologies can be developed.
The development of general construction reactions will have broad utility in a range of fields that rely on the synthesis of small molecules and functional materials. One particular area that the Newhouse group focuses on is the total chemical synthesis of carbocyclic frameworks that are known to elicit powerful neurological effects. These substances will both serve as chemical probes to study fundamental aspects of neurological function and address neurological dysfunction.
We focus our efforts on the development of new synthetic methods to rapidly acquire these structurally complex small molecules. These substances will be exploited for a variety of purposes by collaborating with neuroscientists.

In the Yaghi group we are building chemical structures by stitching molecules together into large and extended frameworks within which we can store hydrogen, methane, and separate carbon dioxide. The interior of the crystals is capable of compacting gases under ambient conditions thus foregoing the use of high pressures and low temperatures. In this movie, crystals of metal-organic framework-5 (MOF-5, numbered in roughly chronological order of discovery) are made and their structure is precisely designed to have zinc oxide units linked by organic struts (terephthalate) to make a porous network into which voluminous gases can be compacted and transported. This large open space is currently being used for positioning of organic and organometallic catalysts, charge storage for supercapacitors and binding of biological molecules such as proteins and metabolites.

Research in the Schanze Labs is focused on the interaction of light with small molecules, polymers, and materials. We have an interest in photochemical and photophysical processes that are stimulated when molecular systems absorb light. Most of our current work centers on studies that explore the phenomenon of luminescence (light emission). In our fundamental work, we apply a variety of spectroscopic methods such as fluorescence spectroscopy and laser-induced time resolved fluorescence spectroscopy to gain information concerning the mechanisms of the light absorption and light emission processes. In applied work, we are using the light emission process of molecules and materials to develop novel light emitting devices (polymer LEDs), and novel fluorescent sensors. Some of our sensor systems are being used by aerodynamics engineers in wind-tunnel and mechanics tests and by chemists and biochemists for sensing analytes of interest.

Enantioselective cooperative catalysis: In the arena of reaction development, we leverage the power of catalysis to engineer new reactivity. Through a synergistic union of Lewis base and transition metal catalysis, we have developed a platform for the enantioselective α‐functionalization of acyclic esters. This protocol effectively addresses long standing issues with control over enolate geometry of acyclic nucleophiles while simultaneously decoupling enantiocontrol – engendered by the Lewis base catalyst – and reactivity, which can be tailored by tuning the ligand sphere around the metal centre. Targeted Synthesis: We are also interested in applying our cooperative catalysis methodology in the area of targeted synthesis in order to identify efficient routes for the synthesis of a variety of natural product and drug-like molecules of biological interest.

Transition metal catalysis continually revolutionizes the synthesis of complex natural products and potential drug candidates by revealing reaction pathways inaccessible via traditional organic transformations. One area of current interest is the development of methodology for the cleavage and functionalization of carbon-carbon bonds. While carbon-carbon single bonds are inert under a vast majority of standard reaction conditions, certain transition metal complexes promote the activation of these bonds.

The Hargrove lab harnesses the unique properties of small organic molecules to study the structure, function and therapeutic potential of long noncoding RNAs (lncRNAs). The discovery of these fascinating biomolecules has caused a paradigm shift in molecular biology and speculation as to their role as the master drivers of diseases such as cancer. At the same time very little is known about their structure and function, leading some to call the field a veritable “Wild West.” Small molecules are the perfect tools for such exploration, and the Hargrove lab works at the interface of chemistry and biology, employing methods ranging from RNA-targeted small molecule synthesis and array-based pattern recognition to studies of the molecular and cellular biology of nucleic acids. Collaborations with the Department of Biology as well as colleagues in the School of Medicine ensure that these tools are applied to the most important unsolved problems in the fundamental biology and disease-related actions of long noncoding RNAs.
