Eichelmann, Robert; Ballmann, Joachim; Gade, Lutz H., 2024, "Tetraazacoronenes and Their Dimers, Trimers and Tetramers [data]", https://doi.org/10.11588/data/ZT3AHN, heiDATA, V1
Tetraazacoronenes were synthesized from bay-functionalized tetraazaperylenes by Zr-mediated cyclization and four-fold Suzuki–Miyaura cross coupling. In the Zr-mediated approach, an η4-cyclobutadiene-zirconium(IV) complex was isolated as an intermediate to cyclobutene-annulated de... |

Uhrmacher, Fabian; Elbert, Sven Michael; Rominger, Frank; Mastalerz, Michael, 2022, "Synthesis of Large [2+3] Salicylimine Cages with Embedded Metal-Salphen Units [Data]", https://doi.org/10.11588/data/LOR2JH, heiDATA, V1
Shape-persistent trinuclear Ni(II)- and Pt(II)-cage compounds with large cavities have been synthesized by using bissalicylaldehyde struts that contain the metal salphen units already. The Pt(II) derivative was investigated by single crystal X-ray diffraction. |

Keck, Christoph; Rominger, Frank; Mastalerz, Michael, 2024, "Synthesis of Chiral Pyrene-Based 1,4-Dithiins [Data]", https://doi.org/10.11588/data/NCRUAV, heiDATA, V1
The 1,4-dithiin motif is known for its reversible redox properties to generate radical cations and diradical dications and thus is interesting for organic electronic applications. However, examples where this motif is embedded into chiral larger fused aromatic compounds is very r... |

Kirschbaum, Tobias; Rominger, Frank; Mastalerz, Michael, 2023, "Synthesis of a Benzotrisazulene via Trioxobenzotrisazulene [data]", https://doi.org/10.11588/data/JE8LF7, heiDATA, V1
A benzotrisazulene was synthesized on the basis of a truxene precursor by a series of Suzuki–Miyaura reactions via the intermediate trisoxo compound. The latter occurs in two forms (syn and anti), and the syn forms porous crystals. |

Hüßler, Christopher; Dietl, Martin C.; Kahle, Justin; Lopes, Eric F.; Kawamura, Miku; Krämer, Petra; Rominger, Frank; Rudolph, Matthias; Hachida, Iwao; Hashmi, A. Stephen K., 2024, "Synthesis and structural properties of para-diselenopyrazines [data]", https://doi.org/10.11588/data/UYS0N6, heiDATA, V1
Recently, dithienopyrazines have emerged as promising building blocks in the field of materials science, showcasing their potential as hole-transport materials in organic electronic devices. Herein, we report the synthesis of its heavier analogues, the diselenopyrazines, along wi... |
Pham, Truc Lam; Kovermann, Michael; Thomas, Franziska, 2022, "Switchable Zinc (II)-Responsive Globular β-Sheet Peptide [Research Data]", https://doi.org/10.11588/data/HV4MJW, heiDATA, V1
The natural function of many proteins depends on their ability to switch their conformation driven by environmental changes. In this work, we present a small, monomeric β-sheet peptide that switches between a molten globule and a folded state through Zn(II) binding. The solvent-e... |

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... |

Maier, Steffen, 2023, "Substituted Cyclopentannulated Tetraazapentacenes [data]", https://doi.org/10.11588/data/AUTKBW, 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... |

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... |
