The next generation of molecular materials with magnetic properties will be strongly based on bridged multinuclear metal complexes (BMMCs) exhibiting single-molecule magnet (SMM) behavior because SMMs are promising building blocks for electronic appliances such as high-density information storage devices and quantum computers. However, SMMs will revolutionize our digital society only if the blocking temperature – an approximate upper limit for the operating temperature of any SMM-based devices – will be significantly increased because all of the currently known SMMs display magnetic properties only at low temperatures.

The research described within this proposal responds to the above demand by investigating BMMCs based on organic redox-active ligands and metal ions possessing a strong axial-magnetic anisotropy such as lanthanide ions. The project aims to establish the relationships between molecular structure, electronic structure, and magnetic properties within the systems studied and seek new ways to enhance the blocking temperatures of SMMs. The obtained results can be used in the rational design of better SMMs based on the same architectures, which might eventually lead to SMMs retaining their magnetic properties at higher temperatures.

The multidisciplinary and international project is built upon the base of research conducted at the Universities of Jyväskylä (principal investigator, Dr. Jani Moilanen; collaborator Prof. Kari Rissanen and collaborator Prof. Heikki M. Tuononen), Leuven (collaborator Prof. Liviu Chibotaru) and Ottawa (collaborator Prof. Muralee Murugesu) and it combines expertise from computational and organometallic chemistry, X-ray crystallography, electrochemistry, and molecular magnetism. This multidisciplinary and scientifically skilled international research team ensure that the project goals can be achieved within the timeframe of the project. Besides the direct research results, the project contributes towards strengthening the status of organometallic chemistry in Finland, establishing a new strategic partnership between the Universities of Jyväskylä and Ottawa (Prof. Murugesu), increasing societal influence by educating the next generation of professional academics, raising the awareness of general public of molecular magnets and organometallic chemistry, and seeking potential stakeholders that can utilize the scientific results obtained in the project.
