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... |

Wagner, Philippe; Rominger, Frank; Gross, Jürgen H.; Mastalerz, Michael, 2023, "Solvent-Controlled Quadruple Catenation of Giant Chiral [8+12] Salicylimine Cubes Driven by Weak Hydrogen Bonding [Data]", https://doi.org/10.11588/data/TIYBD2, heiDATA, V1
A quadruply interlocked catenane has been formed from giant chiral [8+12] salicylimine cubes in a reaction that can be controlled by the reaction solvent. Single-crystal X-ray diffraction revealed hydrogen bonding to be a central driving force for the catenation. Furthermore, scr... |

Tian, Ke; Wang, Xubin; Schuldt, Moritz P.; Elbert, Sven M.; Rominger, Frank; Mastalerz, Michael, 2023, "[4+4]-Imine Cage Compounds with Nitrogen-Rich Cavities and Tetrahedral Geometry [Data]", https://doi.org/10.11588/data/FX6IGS, heiDATA, V1
Organic imine cage compounds have found a variety of different applications in several fields in materials science. To design tailor-made cages for corresponding applications, synthetic approaches to cages with tunable functionalities, sizes and shapes have to be found. Here we 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. |

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... |

Zeitter, Nico; Hippchen, Nikolai; Weidlich, Anna; Jäger, Patrick; Ludwig, Philipp; Dr. Rominger, Frank; Dr. Freudenberg, Jan; Prof. Dr. Dreuw, Andreas; Prof. Dr. Bunz, Uwe H. F, 2023, "Hexakis-TIPS-Alkynylated Nonacenes: Persistent and Processible [data]", https://doi.org/10.11588/data/TFFFN4, heiDATA, V1
We prepared and characterized (UV-vis, epr, X-ray) four substituted nonacenes. They are the most stable and soluble nonacenes to date – due to six strategically placed triisopropylsilyl (TIPS)-ethynyl groups. They are stable for several weeks in the solid state. In dilute solutio... |
