Experimental and theoretical studies of magnetic exchange in silole-bridged diradicals
Five bis(tert-butylnitroxide) diradicals connected by a silole (7a-d) or a thiophene (12) ring as a coupler were studied. Compound 12 crystallizes in the orthorhombic space group Pna21 with a = 20.752(5), b = 5.826(5), and c = 34.309(5) A. X-ra

Tetraarylethylene having two nitroxide groups: Redox-switching of through-bond magnetic interaction by conformation change
Reversible redox-switching of through-bond magnetic interaction has been achieved by conformation change of the tetraarylethylene moiety upon redox input: intramolecular magnetic interaction between two nitroxide groups is dead after oxidation, whereas it
Discrepancy between the spin distribution and the magnetic ground state for a triaminoxyl substituted triphenylphosphine oxide derivative
The magnetic interaction and spin transfer via phosphorus have been investigated for the tri-tert-butylaminoxyl para-substituted triphenylphosphine oxide. For this radical unit, the conjugation existing between the π* orbital of the NO group and the pheny

Nitroxyl-galvinoxyl - a new biradical
The synthesis and solution phase EPR spectrum of a new biradical is presented. The H-hyperfine coupling constants of the biradical indicate interaction of the unpaired electrons in the molecule.
