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.

Doyle Group research focus: Research in our lab takes place at the interface between the fields of organic synthesis, organometallic catalysis, and physical organic chemistry. We are involved in designing synthetic strategies that enable efficient and selective preparation of complex molecules and biologically privileged structural motifs. To achieve these goals, we harness the activity of inexpensive and abundant transition metal catalysts to achieve novel bond-forming processes. Projects in the group are designed to provide students with expertise in reaction discovery and development, while exposing them to problems in complex target synthesis and mechanistic analysis.

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.

Research in the Toste group is primarily aimed toward the development of catalysts, catalytic reactions and methods for organic synthesis. Ultimately, we are interested in using these methods to address problems in the synthesis of complex molecules possessing interesting structural, biological and physical properties. As such, our research program spans the areas of organic synthesis, catalysis, and organometallic chemistry.
