Spin transport is as an essential feature of information processing devices. Organic molecules that contain unpaired electrons, and thereby possess a magnetic moment, can deliver materials that fulfill the requirements of such devices and are cheaper, lighter, and more flexible than metals. The central challenge in this field is the control of spin interactions in three dimensions in a bulk organic material.

Lay summary
This proposal addresses this challenge by designing and investigating carbon-based systems, where spin interactions can be controlled in a precise manner, to improve our understanding of multiple spin interactions and resulting magnetism of molecules and materials. The aim is to construct molecular model systems, where spin interactions can be studied individually ? either through bond or space ? and self-assembled systems, where multiple spin interactions can be studied in a three-dimensional bulk material. By developing molecules and materials based on organic radicals, this project will improve our understanding of spin interactions and aid the development of the next-generation materials for spintronics.
