Holsten, Mattes; Feierabend, Sarah; Elbert, Sven M.; Rominger, Frank; Oeser, Thomas; Mastalerz, Michael, 2022, "Soluble Congeners of Prior Insoluble Shape‐Persistent Imine Cages [Data]", https://doi.org/10.11588/data/E2RPGA, heiDATA, V1
One of the most applied reaction types to synthesize shape‐persistent organic cage compounds is the imine condensation reaction and it is assumed that the formed cages are thermodynamically controlled products due to the reversibility of the imine condensation. However, most of t... |

Holsten, Mattes; Elbert, Sven Michael; Rominger, Frank; Zhang, Wen-Shan; Schröder, Rasmus R.; Mastalerz, Michael, 2023, "Single Crystals of Insoluble Porous Salicylimine Cages [Data]", https://doi.org/10.11588/data/45FZRY, heiDATA, V1
Porous organic cages (POCs) are meanwhile an established class of porous materials. Most of them are soluble to a certain extend and thus processable in or from solution. However, a few of larger salicylimine cages were reported to be insoluble in any organic solvents and thus ch... |

Elbert, Sven Michael; Kirschbaum, Tobias; Rominger, Frank; Mastalerz, Michael, 2022, "Proving Triptycene Homoconjugation with the Same Chromophore but Different Connectivity to the Core [Data]", https://doi.org/10.11588/data/B1JIFI, heiDATA, V1
Homoconjugation is a phenomenon discussed for various π-systems where classical conjugation is broken by e.g. methylene units but still a stabilization by electronic communication exists. In this respect, triptycene with its rigid C3 symmetric geometry is an ideal scaffold to stu... |

Zeitter, Nico; Hippchen, Nikolai; Maier, Steffen; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F.; Dreuw, A, 2022, "Persistent Ambipolar Heptacenes and Their Redox Species [Data]", https://doi.org/10.11588/data/CVD7WF, heiDATA, V1
Research Data associated with the related publication. Sixfold TIPS-ethynylation combined with fourfold bromination of the armchair edges furnishes a long-lived, soluble heptacene; π-extension via Stille coupling accesses a persistent tetrabenzononacene. Both types of acenes were... |

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... |

Popp, Dennis; Elbert, Sven Michael; Barwig, Chantal; Petry, Julian; Rominger, Frank; Mastalerz, Michael, 2023, "Palladium-Catalyzed Cyclization of a Pyryne Precursor to Higher Pyrenylenes [Data]", https://doi.org/10.11588/data/1TCKKG, heiDATA, V1
By palladium-catalyzed oligomerization reactions of pyrene-based o-trimethylsilyl triflates, larger cyclic pyrenylenes were formed with up to 10-membered rings as has been unambiguously characterized by SCXRD. Furthermore, the underlying reaction mechanism has been studied by qua... |

Tian, Ke; Elbert, Sven Michael; Hu, Xinyue; Kirschbaum, Tobias; Zhang, Wen-Shan; Rominger, Frank; Schröder, Rasmus R.; Mastalerz, Michael, 2022, "Highly Selective Adsorption of Perfluorinated Greenhouse Gases by Porous Organic Cages [Data]", https://doi.org/10.11588/data/O9I5UP, heiDATA, V1
Anthropogenic greenhouse gases contribute to global warming. Among those gases, perfluorocarbons (PFCs) are thousands to tens of thousands times more harmful to the environment than comparable amounts of carbon dioxide. Till date, materials that selectively adsorb perfluorocarbon... |
