Summary of main observation and conclusion A facile synthesis, functionalization, and emission property of N‐doped carbon‐rich halogenated compound 3,6,12,15‐tetrachloro‐9‐phenyl‐9H‐tetrabenzo[a,c,g,i]carbazole ( ClCbz ) was reported. Cost‐effective FeCl 3 catalyst serves to break eight C—H bonds of 1,2,3,4,5‐pentaphenylpyrrole ( 1 ) and subsequently construct two C—C and four C—Cl bonds in one pot with a high yield of up to 75%.
