Triplet ground-state organic molecules are interesting with respect to several emerging technologies but typically exhibit limited stability. We report two organic diradicals, one of which possesses a triplet ground state (2J/kB = 234 ± 36 K) and robust stability at elevated temperatures. We are able to sublime this high-spin diradical under high vacuum at 140 °C with no significant decomposition.
三重态基态有机分子在几种新兴技术方面具有重要意义，但通常表现出有限的稳定性。我们报告了两种有机双自由基，其中一种具有三重态基态（2J/kB = 234 ± 36 K）和在高温下的稳健稳定性。我们能够在 140°C 的高真空下升华这种高自旋双自由基，而没有明显的分解。
