Organic radical magnetic materials functionality

Organic radical magnetic materials lacking directional crystal assembly functionality 130... 

The simplest electronic structure models for magnetic interactions only consider the unpaired electrons and their orbitals. All other electrons are taken as inactive and not included in the description. This leads to very simple wave functions, especially in the case of two identical S = magnetic centers. Such valence-only models, where valence is not used in its usual chemical context, are numerically not competitive with large-scale all-electron calculations, but have provided chemists and other scientists working in the field with important insights to control the magnetic interactions in transition metal complexes and materials with organic radicals. 

This chapter gives an introduction to the basic concepts of magnetism in organic paramagnetic soft matter materials. Key concepts are emphasized using example case studies. Detailed analysis covers radicals functionalized with phenols and with benzimidazole functionalities, which induce various degrees of crystal self-assembly, depending on specific structures. A review with over 200 references and notes.
