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 + 0.0007T².
