Abstract
AbstractCarbazoledioxazines with an angular type structure (5,15‐dialkyl‐7,17‐dialkyloxy‐9,19‐dichloro‐5,15‐dihydrodiindolo[2,3‐c:2′,3′‐n]triphenodioxazines) were selectively synthesized by electrochemical oxidative ring closure of precursors (2,5‐bis(9‐alkyl‐2‐alkyloxy‐3‐carbazolylamino)‐3,6‐dichloro‐1,4‐benzoquinones). The structure was confirmed by 1H‐nmr and other instrumental analyses. Their thermal properties and solubilities were investigated and were compared with those of carbazoledioxazines with a linear type structure.
