Abstract
An island of unusual electronic properties: In their Communication (e202506305), Max M. Hansmann et al. design a new platform for N-heterocyclic olefins, their unique intramolecular cyclization and the paratropic ring current of the tricyclic products, represented by dolphins jumping in between the quinolizine ring. The follow-up oxidation leads to a stable fluorescent organic radical.
