A range of aza‐ullazines, which represent a new heterocyclic core structure, were synthesized through a scalable four‐step reaction, including a Sonogashira reaction and metal‐free cyclization promoted by p‐toluenesulfonic acid. The optical and electrochemical properties of selected derivatives were investigated, they were found to have similar absorption and emission spectra but a higher oxidation potential than the parent ullazine core.
