Self-assembled covalent-organic frameworks (COFs) are a cutting-edge approach for exploring novel magnetic properties due to their well-defined, two-dimensional structures and customizable chemical environments. Their unique geometry supports the study of frustrated magnetism, where competing interactions hinder the system from minimizing all forces simultaneously, leading to intriguing quantum spin liquid (QSL) phases. These phases are promising for quantum computing due to their potential for robust qubits and fault-tolerant computation. Unlike bulk materials or multilayer structures, which often face challenges such as uncontrollable defects that can quench quantum properties, COFs on surfaces offer an ideal platform. They provide precise control over lattice symmetry and magnetic interactions while avoiding synthesis complexities and defects. This proposal aims to advance research by developing a novel COF with a frustrated Kagomé-honeycomb (KH) lattice. The originality of this approach lies in combining surface-supported COF synthesis with innovative methods for tuning frustrated magnetism. Specifically, an organic radical linker covalently bonded with inorganic molecular magnets allows for precise tuning of exchange interactions. This is achieved by controlling the spatial overlap between the radical and metal centers through fine-tuning the noble metal substrate’s work function via chemical passivation, enabling reversible switching between different charge states of the radical linker. By creating a model system for controlling magnetic interactions, this approach enhances our ability to manipulate frustrated magnetic ground states on surfaces. It opens new avenues for understanding magnetism and chemistry, with potential applications in topological quantum computing, data storage, and spintronic devices.

The MASTERPIECE project aims to create a transformative change in the conservation of Wooden Panel Paintings (WPPs) from the Middle Ages and Renaissance, integral to our shared cultural heritage. These artworks are susceptible to environmental conditions like humidity and temperature fluctuations, challenging traditional conservation methods. The project proposes an innovative approach by integrating energy-efficient climate control and advanced digital modeling to optimize both preservation and sustainability. Traditional climate control systems in museums contribute to an unsustainable energy footprint. MASTERPIECE addresses this by using adaptive climate control strategies that take into account the unique needs of each artwork. Through collaboration with the Getty Conservation Institute (GCI), a leader in art conservation, the project will develop 'digital twins'—digital replicas that simulate the artworks' hygro-mechanical behavior in real-time. Rather than focusing solely on vulnerability, MASTERPIECE introduces the concept of resilience through 'fragility-resilience curves.' These curves enable a nuanced understanding of how artworks respond to environmental stressors, informing targeted and effective conservation strategies that harmonize with energy efficiency goals. The project will unfold in two key phases. The first phase at the GCI will focus on creating the digital twins and fragility-resilience curves. The second phase will conduct mechanical characterization tests on historical paintings to validate and refine these models, ensuring their broader applicability and impact. MASTERPIECE aims to redefine standards in art conservation by offering an interdisciplinary solution that harmonizes the need for energy-efficient practices with effective long-term preservation. By integrating advanced technologies with conservation science, MASTERPIECE aspires to make a lasting, positive impact on global art preservation strategies.
