Thermolysis of Biphenylene toward Cyclo-ortho-phenylenes [data] Mar 4, 2024 - Bunz Group 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...
Efficient Intramolecular Singlet Fission in Spiro-Linked Heterodimers [research data] Mar 15, 2024 - SFB 1249: N-Heteropolyzyklen als Funktionsmaterialien - B: Theory & Structure 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...
Dispersion-Driven Formation of Chiral Twisted PAH Double Helices [Data] Mar 20, 2024 - Institute of Organic Chemistry - AK Mastalerz 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...
Synthesis and structural properties of para-diselenopyrazines [data] Mar 26, 2024 - SFB 1249: N-Heteropolyzyklen als Funktionsmaterialien - A: Synthesis 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...
