Glycosylation is a reaction used by Nature to modulate the structure and function of biomolecules. Most human viruses and cancer cells, for example, depend on the host glycosylation machinery to create a sugar coat on the cell surface to complete their life cycle and escape immune response. Understanding the role of cell surface glycans in viral infection, cancer progression and immune response requires easy access to this class of complex materials. This lecture will present our recent development of efficient and environmentally friendly chemoenzymatic methods for the synthesis of complex carbohydrates and glycoproteins and development of low-sugar universal vaccines and glycoengineered antibodies with improved Fc-mediated killing.

Direct arylation polymerization (DArP) has gained significant attention for synthesizing conjugated polymers, offering advantages over conventional cross-coupling methods. DArP reduces organometallic waste and eliminates the need for prefunctionalization, thus enhancing atom economy. It generates benign by-products and requires only halogen-functionalization of one monomer. However, challenges in achieving selectivity and control during polymerization persist.

To address these issues, our group explored synergistic catalysis using Pd/Ag or Au/Ag combinations. This approach enables reactions previously unattainable with single catalysts. We initially focused on developing a controlled DArP to produce polymers with targeted molecular weights and low dispersities. Using dual catalysts, one for C-H activation and another for controlled polymerization, we demonstrated some living characteristics, albeit with low molecular weights.

We extended this work to donor-acceptor copolymer synthesis via cross dehydrogenative coupling (CDC). Unlike standard DArP, which couples C-Br and C-H groups, CDC involves C-H/C-H coupling, where selectivity is critical to avoid homocoupling products. Employing a Pd/Ag cocatalyst system, we achieved high selectivity, producing high molecular weight polymers with minimal defects. The second chain-extension cross-coupling occurred at least an order of magnitude faster than the first coupling or homocoupling side reactions. DFT calculations revealed that the enhanced rate of cross-coupling in the second step stems from a strong Pd-thiophene interaction, which lowers the energy barrier for Pd-mediated C-H activation. These findings not only improve polymerization processes but also have broader applications in synthesizing complex molecules where C-H bond activation is challenging.

The current era has seen truly paradigm shifting scientific developments. We also know that the size of small molecule and materials spaces is for all practical purposes infinite, providing an inexhaustible supply of potential drugs and materials with valuable properties if we can find them. This recognition has seen a rapid increase in automation and robotics, allowing synthesis of new molecules and materials and measurement of properties orders of magnitude faster than before, generating massive databases of complex genetic, structural, chemical, property, and biological information.

The need to find ‘islands of chemical utility’ in an almost infinite palette of possibilities has seen the development of new data-driven machine learning methods (ML), like deep learning and large language models (LLMs), and an unprecedented increase in their applications. ML algorithms are universal approximators, prompting a parallel rise in their applications to most other aspects of modern life – medicine, finance, manufacturing, social media etc. we now have rapid and accurate quantum machine learning methods, generative methods that use trained machine learning models to suggest new molecules or materials with improved properties, accurate prediction of protein structures from sequence using AlphaFold and similar, the beginnings of general AI in LLMs like ChatGPT, massive ‘make on demand’ chemical libraries such as ZINC-22, nascent autonomous chemical discovery systems, and a rise in evolutionary AI methods for molecule and materials discovery.

This paper will discuss the drivers for these exciting developments and give examples where my collaborators and I have used AI and machine learning in biomaterials and regenerative medicine, drug design, energy materials and nanomaterials, cancer diagnostics, and corrosion control.

Topic of Presentation: Cinematic Chemistry: The Journey of Electron Microscopy from Organic Synthesis to Molecular Statistics

Recent technological innovations in electron microscopy, such as aberration correctors, high-speed imaging cameras, and continuous sample rotation, have ushered in a new era where we can, for the first time, analyze the behavior of individual molecules. In this lecture, I will introduce the new paradigm of “cinematic chemistry,” which has emerged from the single-molecule atomic-resolution time-resolved electron microscopy (SMART-TEM). I will use examples from single-molecule thermodynamics and kinetics based on ultra-fast imaging of individual molecules and reaction events, in situ structural and statistical analysis of crystal growth, and the mechanisms behind organic crystal disorder during electron diffraction experiments that has long confused electron microscopists. Our recent study has shown that the kinetics of electron diffraction peak decay provides quantitative information about the degree of freedom of the molecules in a crystal.

Topic of Presentation: From Coherence in Photosynthesis to Chemical Quantum Information Science

Gregory D. Scholes, Princeton University

The parallel and synergistic developments of atomic resolution structural information, new spectroscopic methods, their underpinning formalism, and the application of sophisticated theoretical methods have led to a step function change in our understanding of photosynthetic light harvesting. These new spectroscopic methods, in particular multidimensional spectroscopies, have enabled a transition from recording rates of processes to focusing on mechanism. Such studies indicated the possibility that advanced ultrafast techniques can give insights into the time evolution of the density matrix of the system. I will explain the story of how our understanding of these experiments evolved. We then ask, how might related developments enable advances in quantum information science? A defining characteristic of molecules is that they are intrinsically complex quantum systems with many degrees of freedom, exhibiting remarkable variety. Molecules, therefore, have different quantum properties than atomic systems, including solids. Our aim in in chemical quantum information science (QIS) should then be to leverage these distinctions. This is where transformative advancements lie. I will outline and motivate the QIS “wish list” for chemistry that we described in a recent report.

Nanostructured materials can be designed with sophisticated features to fulfill the complex requirements of advanced material applications. Our laboratory has developed organic and inorganic nanoparticles and nanocomposites for advanced drug delivery, antimicrobial, stem cell culture, and tissue engineering applications. In addition, we have nanofabricated microfluidic systems for drug screening, in vitro toxicology, and diagnostic applications. The nanosystems allow for the rapid and automated processing of drug candidates and clinical samples in tiny volumes, greatly facilitating drug testing, genotyping assays, infectious disease detection, point-of-care monitoring, as well as cancer diagnosis and prognosis.

We have also synthesized metallic, metal oxide and semiconducting nanoclusters, nanocrystals and nanosheets of controlled dimensions and morphology. The nano-sized building blocks are used to create multifunctional systems with excellent dispersion and unique properties. Nanoporous materials of a variety of metal oxide and organic backbone have also been created with high surface areas and well-defined porosities. These nanostructured materials are successfully tailored towards energy and sustainability applications.

The dynamics of infectious disease (ID) require fast accurate diagnosis for effective management and treatment. Without in-vitro diagnostics (IVDs) syndromic or presumptive actions are followed, where positive cases may go undetected in the community, or mistreated due to wrong diagnosis. This undermines effective clinical decision-making and disease containment. However, biosensor-diagnostics used in low and middle income countries (LMICs) usually have to be imported at high cost, making their use prohibitive. 

The required biological reagents for a diagnostic are typically the largest proportion of the cost (50-95%). Taking a ‘gene to diagnostic’ approach, a rational design will be reported for a diagnostic platform that can be manufactured locally, with basic infrastructure. We use synthetic biology to design multifunctional fusion-enzymes for point-of-care diagnostics with locally resourced materials. 

The platform is demonstrated for nucleic acid amplification tests (NAATs) requiring a DNA polymerase fusion protein which can be isolated on silica via a fused R5 silica-affinity peptide. Data from a clinical study of malaria are presented and the results discussed in comparison with qPCR, providing the first step towards low cost diagnostics in resource poor areas. This could deliver a sustained improvement in healthcare, while also developing the local economy.

Earth system science makes it increasingly clear that the scale and kinetics of anthropogenic transformation of matter have rapidly pushed the control variables for interconnected Earth systems closer to tipping points. The planetary sustainability and human security challenges facing our planet are so pressing that they require urgent attention by all of humanity through a convergence of disciplinary and cross-sectoral approaches. Chemistry, the science of transformation of matter, has a pivotal role to play in addressing the unintended consequences that arise from the large-scale material transformation by humans over the past fifty years. As the World Chemistry Congress begins, with a theme of “Chemistry for Our Sustainable Future,” we can no longer see sustainability and the contributions of our central science as a goal, but rather an imperative.

The clock is ticking as we rapidly approach the target dates for meeting the UN Sustainable Development goals (2030) and the 2050 global energy net-zero agreements to mitigate the impact of humans on the energy balance of our planet. What re-imagining of chemistry education, research, and industry must we collectively embrace to practice chemistry responsibly in our rapidly changing world? IUPAC, through activities and structures that unite chemists and chemistry educators worldwide, plays a strategic role in guiding chemistry education, research and practice toward the emergence of sustainability. We will highlight IUPAC projects that:

(a) resource implementation of systems thinking in chemistry for sustainability with strands focused on chemistry as a sustainability science, formal chemistry education, and chemical industry; and

(b) introduce principles to guide chemists in the responsible practice of chemistry, informed by our pressing sustainability challenges and ethics, diversity, equity, and inclusion values. The project task group will formally launch the “IUPAC Guiding Principles of Responsible Chemistry” website at this Congress.

Topic of Presentation: Continuous Movement of Carbon Atoms in Organic Molecules: Merry-Go-Round Reaction

Continuous movement of carbon atoms in organic molecules is a challenging target in chemistry. I proposed a new concept to achieve such movement using equilibrium of two organic molecules where positions of carbon atoms are not the same. Even though the mechanism of the equilibrium is not clear, more stable compound is formed among the molecules in the equilibrium by moving of the target carbon atoms in the organic molecules.

I applied this new concept for dihydroindenyl moiety on titanium, and I could developed that two red carbons at the bridge-head positions of dihydroindenyl moved around the six-membered ring. I named this reaction, “Merry-Go-Round Reaction”.
