Ludwig, Philipp; Mayer, Jacob; Ahrens, Lukas; Rominger, Frank; Ligorio, Giovanni; Hermerschmidt, Felix; List-Kratochvil, Emil J.W.; Freudenberg, Jan; Bunz, Uwe H.F., 2023, "Doubly Bridged Anthracenes: Blue Emitters for OLEDs [data]",, heiDATA, V1
The photooxidative stability of a series of doubly bridged anthracenes was evaluated after their preparation via twofold macrocyclization of a bis(resorcinyl)anthracene. Lightfastness correlates with the energy levels of the highest occupied molecular orbital (HOMO), resulting in...

Zeitter, Nico; Hippchen, Nikolai; Weidlich, Anna; Jäger, Patrick; Ludwig, Philipp; Dr. Rominger, Frank; Dr. Freudenberg, Jan; Prof. Dr. Dreuw, Andreas; Prof. Dr. Bunz, Uwe H. F, 2023, "Hexakis-TIPS-Alkynylated Nonacenes: Persistent and Processible [data]",, heiDATA, V1
We prepared and characterized (UV-vis, epr, X-ray) four substituted nonacenes. They are the most stable and soluble nonacenes to date – due to six strategically placed triisopropylsilyl (TIPS)-ethynyl groups. They are stable for several weeks in the solid state. In dilute solutio...

Two series of regioisomeric dicyanomethylene substituted dithienodiazatetracenes with formal para- or ortho- quinodimethane subunits were synthesized and characterized. Whereas the para-isomers (p-n, diradical index y0=0.01) are stable and isolable, the ortho-isomer (y0=0.98) dim...

Ahrens, Lukas; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2023, "Etheno-bridged Azaacene Spiro Dimers [data]",, heiDATA, V1
We present the synthesis of two sets of spiro-connected azaacene dimers. Their geometry and electronic coupling are critically determined by a secondary linker, i.e. an etheno- and an ethano-bridge.The core fragment of the etheno-bridged dimer corresponds to a conformationally lo...

F., 2023, "Second Generation of Cata-Annulated Azaacene Bisimides: Towards Electron Accepting Materials [research data]",, heiDATA, V1
Herein we provide the reserach data for the puplication: "Second Generation of Cata-Annulated Azaacene Bisimides: Towards Electron Accepting Materials". Where we present the second generation of cata-annulated azaacene bisimides with increased electron affinities compared to thei...

Marder; Jan Freudenberg; Uwe H. F. Bunz, 2023, "The Radical Anion and Dianion of Benzo[3,4]cyclobuta[1,2-b]phenazine [NMR data]",, heiDATA, V1
The data set includes the NMR data for the puplication: "The Radical Anion and Dianion of Benzo[3,4]cyclobuta[1,2-b]phenazine". We present the reduction of two azaarenes, featuring a single cyclobutadiene unit, to their radical anions and dianions. The reduced species were prepar...

Maier, Steffen, 2023, "Substituted Cyclopentannulated Tetraazapentacenes [data]",, heiDATA, V1
Brominated pentannulated dihydrotetraazapentacenes were prepared by gold- or palladium-catalyzed 5-endo-dig cyclization of TIPS-ethynylated dihydrotetraazaacenes (TIPS = triisopropylsilyl). Post-functionalization was demonstrated by Sonogashira alkynylation and Rosenmund-von Brau...

Maier, Steffen, 2023, "Azaarenes: 13 Rings in a Row by Cyclopentannulation [data]",, heiDATA, V1
Cyclopentannulation was explored as a strategy to access large, stable azaarenes. Buchwald-Hartwig coupling of previously reported di- and tetrabrominated cyclopentannulated N,N'-dihydrotetraazapentacenes furnished stable azaarenes with up to 13 six-membered rings in a row and a...

Wiesner, Thomas, 2022, "N-Acenoacenes: Synthesis and Solid-State Properties [Data]",, heiDATA, V1
Four N-acenoacenes were synthesized and analyzed for their optoelectronic properties and solid-state packings. Two of the regioisomeric acridinoacridines are TIPS-ethynylated, whereas the other pair are Boc- and triflate substituted derivatives. The two TIPS- ethynyldiazaacenoace...
