Organische Tri‐ und Tetraradikale in High‐Spin‐oder Low‐Spin‐Zuständen

Abstract: Die Werkzeugkiste des Spinkopplers ist gut ausgestattet, denn für nahezu alle möglichen Topologien von organischen Tri‐ und Tetraradikalen sind inzwischen Beispiele bekannt, die als Bausteine in der Synthese praktisch anwendbarer Polyradikalmaterialien eingesetzt werden können. High‐Spin‐Polyradikale könnten als organische Ferromagnete nützlich sein, während manche Low‐Spin‐Polyradikale vermutlich elektrisch leitfähig sind, z.B. die Derivate des Singulett‐Tetraradikals 1, in dem sowohl ferromagnetische als auc… Show more

“…The properties of high-spin molecules are currently of enormous interest due to their potential applications in molecular magnets. Although the high reactivity of 1 most probably excludes its use in such applications, the investigation of the interplay among the two spin-carrying moieties in dehydrophenylnitrenes and the factors governing the electronic ground states is needed for an understanding of these molecules. We therefore decided to investigate in this paper by multiconfiguration quantum chemical means the parent C 6 H 4 N 4-, 3-, and 2-dehydrophenylnitrenes ( 3 , 4 , and 5 , Chart ) rather than the perfluorinated species considered in the experimental work.…”
