Ahrens, Lukas; Tverskoy, Olena; Weigold, Svenja; Ganschow, Michael; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2024, "(Aza)Pentacenes Clipped into a Ring: Stabilization of Large (Aza)Acenes [data]", https://doi.org/10.11588/data/5VN0H0, heiDATA, V1
A doubly alkylene bridged 6,13-diphenylpentacene and analogously bridged azapentacenes were prepared; they are persistent. The doubly bridged azapentacenes display superior photochemical, oxidative and thermal stabilities compared to azapentacenes protected by bis(TIPS-ethynyl)-s... |

Yang, Xuan; Brückner, Margit; Rominger, Frank; Kirschbaum, Tobias; Mastalerz, Michael, 2024, "Dispersion-Driven Formation of Chiral Twisted PAH Double Helices [Data]", https://doi.org/10.11588/data/BRM2DI, heiDATA, V1
Molecular double helices are ubiquitous in nature and have also been generated artificially. These are usually based on helical ribbons. Here, a new type of double helices based on twisted ribbons is introduced. The monomeric strands are polycyclic aromatic hydrocarbons of variou... |

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... |

Chabai, Victor; Dudnyk, Diana; Pasda, Kerstin; Brandl, Michael; Maier, Andreas, 2024, "Ergänzungsmaterial zu: Investigations at the Epigravettian site of Barmaky in Volhynia, north-west Ukraine: analyses and taxonomic reflections", https://doi.org/10.11588/data/Z6B1KV, heiDATA, V1
Known since 1981 and investigated in several campaigns between 1982 and 2007, the site of Barmaky in north-west Ukraine has recently been the subject of renewed investigations from 2018 to 2020. The assemblage is strikingly similar to the one reported from the famous site of Mizy... |
