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... |

Hashmi, A. Stephen K.; Hüßler, Christopher; Kahle, Justin; Dietl, Martin C.; Krämer, Petra; Rominger, Frank; Rudolph, Matthias, 2024, "Facile two-step Synthesis of para-Dithienopyrazines [data]", https://doi.org/10.11588/data/14RXKL, heiDATA, V1
N-Heteropolycyclic compounds are valuable building blocks in organic electronic devices. In this work, a convenient route for the synthesis of para-dithienopyrazines from readily available starting materials is described. A cascade of nucleophilic aromatic substitution and subseq... |

Ludwig, Philipp; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2024, "Stabilization of Acenes: “Geländer”-Pentacenes [data]", https://doi.org/10.11588/data/NITIKZ, heiDATA, V1
We report soluble tetrakis-biphenyl substituted pentacenes comprised of sp2 carbons and synthesized from pentacene-5,7,12,14-tetraone. Intramolecular Yamamoto coupling of two tetrakis(chlorobiphenylyl)pentacenes yields helical, doubly wrapped pentacenes, in which the quaterphenyl... |

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... |

Riedmiller, Kai; Reiser, Patrick; Bobkova, Elizaveta; Maltsev, Kiril; Gryn’ova, Ganna; Friederich, Pascal; Gräter, Frauke, 2023, "Substituting density functional theory in reaction barrier calculations for hydrogen atom transfer in proteins [data]", https://doi.org/10.11588/data/TGDD4Y, heiDATA, V2
Hydrogen atom transfer (HAT) reactions are important in many biological systems. As these reactions are hard to observe experimentally, it is of high interest to shed light on them using simulations. Here, we present a machine learning model based on graph neural networks for the... |

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]", https://doi.org/10.11588/data/1MXYDJ, 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... |

The search for sustainable polymer systems is key to tackling the current climate crisis. However, the use of bio-based polymers does not suffice to achieve this goal. Additionally, new chemical approaches enabling the re- or upcycling of polymer materials need to be explored. He... |
