One pot syntheses of substituted dibenzothiophene S,S-dioxides and fluorenones were successfully achieved by Diels–Alder reaction of benzo[c]furans with thiophene S,S-dioxides and indenones, respectively. Photophysical properties of representative seven- and nine-membered dibenzothiophene S,S-dioxide acenes were also reported.
