摘要
一个不寻常的电子性质岛：在他们的Communication （e202506305）中，Max M. Hansmann等人设计了一个新的n -杂环烯烃平台，其独特的分子内环化和三环产物的异向环电流，以海豚在喹啉环之间跳跃为代表。后续氧化产生稳定的荧光有机自由基。

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.
