Singlet–triplet bistability in a 1,3-phenylene-based bis(aminoxyl) diradical

Abstract

Rapid quenching of the title bis(aminoxyl) 1 in 2-methyltetrahydrofuran from ambient temperature to cryogenic temperatures (5 K or below) produces 1 in its singlet state, which slowly converts at low temperatures, with an S-shaped time-dependence, to the triplet ground state.

13. A Quantum Design MPMS5S SQUID instrument was used with either standard or continuous temperature control. An approximate correction for diamagnetism (χ_dia) for each sample was obtained from extrapolation of χ vs. 1/T(χ= total magnetic susceptibility) plots using the data in the T= 160–280 K range in the cooling mode of the MPMS5S. Typical values χ_dia≈ 4 × 10^–8 emu are an order of magnitude less than the total χ in the 5–1.8 K range.
14. The estimate of the Heisenberg coupling constant, J/k= 40 K (Fig. 2), can only be very approximate, as conformational effects may interfere with a simple two-state model.
