Dimethylnonacethrene – en route to a magnetic switch?
Chemical Communications Pub Date: 2023-05-17 DOI: 10.1039/D3CC01301D
Abstract
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.
