Scientific Scope – Spins in Molecular Systems 2025

The international conference "Spins in Molecular Systems 2025 (SiMS 2025)" aims to bring together leading researchers across chemistry, physics, and materials science to discuss the latest breakthroughs in understanding and manipulating spin degrees of freedom in molecular frameworks. This rapidly evolving field lies at the interface of quantum materials, molecular magnetism, and functional molecular systems, and plays a pivotal role in the development of next-generation technologies ranging from quantum computing and spintronics to smart sensors and memory devices.

Scope and Themes

The conference will provide a comprehensive overview of the theoretical, computational, and experimental advances in molecular spin systems, including both fundamental mechanisms and emerging applications. Topics include, but are not limited to:

1. Molecular Spin Crossover and Spin-State Switching

• Spin crossover (SCO) phenomena in Fe(II), Co(II), and other transition metal complexes.
• Thermally and photoinduced spin transitions (LIESST and reverse-LIESST effects).
• Kinetics, cooperativity, and domain dynamics in spin transition materials.
• Advanced spectroscopic techniques (optical, Mössbauer, EPR, XAS) to probe spin states.
• Influence of solvation, pressure, and crystallographic phase transitions on spin behavior.

2. Single-Molecule Magnets and Qubits

• Design and synthesis of lanthanide- and transition-metal-based single-molecule magnets (SMMs).
• Spin–phonon coupling and decoherence in molecular qubits.
• Strategies to enhance spin coherence lifetimes.
• Integration of SMMs into solid-state platforms and surfaces.

3. Molecular Spintronics and Magnetic Devices

• Hybrid molecular/inorganic spintronic devices.
• Spin transport and injection in molecular junctions.
• Electron spin resonance and magnetic readout techniques.
• Interface effects and magnetic anisotropy at the molecular scale.

4. Theoretical and Computational Advances

• Ab initio and DFT-based modeling of spin states and exchange interactions.
• Non-adiabatic dynamics and vibronic coupling in spin-active molecules.
• Quantum simulations of spin crossover and tunneling mechanisms.
• Machine learning in spin material discovery and phase prediction.

5. Stimuli-Responsive Molecular Materials

• Multifunctional systems with magnetic, optical, electronic, and mechanical coupling.
• External control via light, electric field, pressure, and guest inclusion.
• Bistability, hysteresis, and memory effects in molecular solids.
• Structural dynamics and phase transitions monitored by ultrafast and time-resolved techniques.

6. Emerging Applications

• Spin-based molecular sensors and actuators.
• Quantum information processing using spin-active molecules.
• Design of spin logic devices and molecular memory units.
• Integration of molecular spins in flexible and nano-patterned substrates.

This conference fosters cross-disciplinary collaboration, uniting synthetic chemists who design and engineer spin-active molecules, experimental physicists who explore spin phenomena under diverse external stimuli, and materials scientists who develop functional materials and device architectures. Discussions will highlight how advances in structural characterization, quantum control, and multiscale modeling synergize to push the boundaries of molecular spin systems.

Through invited talks and poster sessions, "Spins in Molecular Systems 2025" will serve as a dynamic platform to explore the frontiers of spin science and shape future directions in the design and implementation of molecular spin technologies.
