Dimethylnonacethrene is the first derivative of the cethrene family that is energetically more stable than the product of its electrocyclic ring closure. Compared to the shorter homologue dimethylcethrene, the new system is EPR-active, because of a significantly lowered singlet-triplet gap, and displays remarkable stability. Our results suggest that adjustment of the steric bulk in the fjord region can enable realisation of diradicaloid-based magnetic photoswitches.
二甲基壬烯是 cethrene 家族的第一个衍生物，其能量稳定性高于其电环化环闭的产物。与较短的同系物二甲基乙撑基相比，由于单重态-三重态能隙显著降低，新体系具有 EPR 活性，并表现出显著的稳定性。我们的结果表明，在峡湾区域调整位阻可以实现基于双自由基的磁性光开关。
