Zong, Wansheng; Hippchen, Nikolai; Nico, Zeitter; Maier, Steffen; Philipp, Ludwig; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2024, "Stable Azaheptacenes", https://doi.org/10.11588/data/P9AVCU, heiDATA, V1
we have developed a novel access to stable azaheptacenes and investigated both their (air-stable) radical anions as well as dianions. The two azaheptacenes are significantly more stable than reported examples. We identified their structure through NMR, IR, MS and X-ray crystallog... |

Zeitter, Nico; Hippchen, Nikolai; Baur, Philipp; Unterreiner, Tamara; Freudenberg, Jan; Rominger, Frank; Bunz, Uwe, 2024, "Pentacene to Octacene: The Limit of Fourfold TIPS-Ethynylation [data]", https://doi.org/10.11588/data/DDJFGS, heiDATA, V1
Soluble acenes beyond hexacene are rare. Their sensitivity complicates isolation, purification and application in devices. To increase the stability of acenes, functionalization with trialkylsilylethynyl substituents prevents [4+4] dimerization and oxidation. At the same time suc... |
Zong, Wansheng; Hippchen, Nikolai; Dittmar, Benedikt; Elter, Maximilian; Ludwig, Philipp; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2024, "Halogenated Phenazinothiadiazoles: Electron Transporting Materials [data]", https://doi.org/10.11588/data/PKX5CI, heiDATA, V1, UNF:6:M6UVaar224tmBy3Sj1o9jg== [fileUNF]
Triisopropylsilyl-(TIPS)-alkynylated phenazinothiadiazoles were prepared by the condensation of halogenated ortho-quinones and TIPS-alkynylated 5,6-diamino-2,1,3-benzothiadiazole with different combinations of halogen substituents. The compounds pack in brickwall motif of head-to... |

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]", https://doi.org/10.11588/data/TFFFN4, 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... |

F., 2023, "Second Generation of Cata-Annulated Azaacene Bisimides: Towards Electron Accepting Materials [research data]", https://doi.org/10.11588/data/U9IRYY, 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... |

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... |
