Fuchs, Kathleen; Dr. Rivero, Samara M.; Weidlich, Anna; Dr. Rominger, Frank; Israel, Noel; Dr. Popov, Alexey A.; Prof. Dreuw, Andreas; Dr. Freudenberg, Jan; Prof. Casado, Juan; Prof. Bunz, Uwe, 2023, "Dimerization of a Reactive Azaacene Diradical: Synthesis of a Covalent Azaacene Cage [Data]", https://doi.org/10.11588/data/QO118B, heiDATA, V1
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... |

Wiesner, Thomas; Wu, Zhu; Han, Jie; Ji, Lei; Friedrich, Alexandra; Krummenacher, Ivo; Moos, Michael; Lambert, Christoph; Braunschweig, Holger; Rudin, Benjamin; Reiss, Hilmar; Tverskoy, Olena; Rominger, Frank; Dreuw, Andreas; Marder, Todd; Freudenberg, Jan; Bunz, Uwe, 2022, "The Radical Anion, Dianion and Electron Transport Properties of Tetraiodo-Tetraazapentacene [Data]", https://doi.org/10.11588/data/S0KS2I, heiDATA, V1
Tetraiodotetraazapentacene I4TAP , the last missing derivative in the series of halogenated silylated tetraazapentacenes, was synthesized via condensation chemistry from a TIPS-ethynylated diaminobenzothiadiazol in three steps. Single and double reduction furnished its air-stable... |

Maier, Steffen, 2022, "A Stable Hexaazaoctacene Cruciform σ-Dimer [Data]", https://doi.org/10.11588/data/FABJEI, heiDATA, V1
Buchwald‐Hartwig coupling of a triisopropylsilyl (TIPS)‐ethynylated dibromo‐N,N'‐dihydrotetraazapentacene with 1,4‐bis(TIPS‐ethynyl)‐2,3‐diaminonaphthalene furnishes a dihydrohexaazaoctacene. Its oxidation with MnO2 results in a 7,7'‐bi(hexaazaoctacenyl). In addition to eight TIP... |

Zeitter, Nico; Hippchen, Nikolai; Maier, Steffen; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F.; Dreuw, A, 2022, "Persistent Ambipolar Heptacenes and Their Redox Species [Data]", https://doi.org/10.11588/data/CVD7WF, heiDATA, V1
Research Data associated with the related publication. Sixfold TIPS-ethynylation combined with fourfold bromination of the armchair edges furnishes a long-lived, soluble heptacene; π-extension via Stille coupling accesses a persistent tetrabenzononacene. Both types of acenes were... |
