Elter, Maximilian; Ahrens, Lukas; Luo, Stella M.; Rominger, Frank; Freudenberg, Jan; Cao, Dennis D.; Bunz, Uwe H. F., 2024, "Cata-Annulated Azaacene Bisimides [data]",, heiDATA, V1
Ultra-electron-deficient azaacenes were synthesized via Buchwald-Hartwig coupling of ortho-diaminoarenes with chlorinated mellophanic diimide followed by oxidation of the intermediate N,N’-dihydro compounds with MnO2 or PbO2. The resulting cata-annulated bisimide azaacenes have u...

A doubly alkylene bridged 6,13-diphenylpentacene and analogously bridged azapentacenes were prepared; they are persistent. The doubly bridged azapentacenes display superior photochemical, oxidative and thermal stabilities compared to azapentacenes protected by bis(TIPS-ethynyl)-s...
