Abstract

7-(Fur-2-yl)benzotriazinyl 1 is the first example of a hydrazyl radical dimer with a thermally accessible triplet state. The triplet exciton (D = 0.018 cm-1, E = 0.001 cm-1) was observed by solid-state VT-EPR spectroscopy between 5 and 140 K. VT crystallography, DFT calculations and magnetic susceptibility studies reveal a strong temperature dependence of the intra-dimer exchange interaction with J / k ∼ -254 + 0.0007T 2.
