Ehjeij, Daniel; Rominger, Frank; Bunz, Uwe; Freudenberg, Jan; Müllen, Klaus, 2024, "Thermolysis of Biphenylene toward Cyclo-ortho-phenylenes [data]", https://doi.org/10.11588/data/AYVNYK, heiDATA, V1
The solvent and catalyst free thermolysis of biphenylenes at 350 °C furnishes [n]cyclo-ortho-phenylenes ([n]COPs, n=4–10) in one step and in high yields. At 400 °C biphenylene dimerizes into tetraphenylene, but lower reaction temperatures produce cyclooligomers. If suitably subst... |

Kefer, Oskar; Ahrens, Lukas; Han, Jie; Wollscheid, Nikolaus; Misselwitz, Erik; Rominger, Frank; Freudenberg, Jan; Dreuw, Andreas; Bunz, Uwe H. F.; Buckup, Tiago, 2024, "Efficient Intramolecular Singlet Fission in Spiro-Linked Heterodimers [research data]", https://doi.org/10.11588/data/HMRSVO, heiDATA, V1
We investigate intramolecular singlet fission (iSF) of spiro-linked azaacene heterodimers by time-resolved spectroscopy and quantum chemical calculations. Combining two different azaacenes through a nonconjugated linker using condensation chemistry furnishes azaacene heterodimers... |

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... |

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... |
