Ludwig, Philipp; Mayer, Jacob; Ahrens, Lukas; Rominger, Frank; Ligorio, Giovanni; Hermerschmidt, Felix; List-Kratochvil, Emil J.W.; Freudenberg, Jan; Bunz, Uwe H.F., 2023, "Doubly Bridged Anthracenes: Blue Emitters for OLEDs [data]", https://doi.org/10.11588/data/1MXYDJ, heiDATA, V1
The photooxidative stability of a series of doubly bridged anthracenes was evaluated after their preparation via twofold macrocyclization of a bis(resorcinyl)anthracene. Lightfastness correlates with the energy levels of the highest occupied molecular orbital (HOMO), resulting in... |

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... |

Ahrens, Lukas; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2023, "Etheno-bridged Azaacene Spiro Dimers [data]", https://doi.org/10.11588/data/L8NDRO, heiDATA, V1
We present the synthesis of two sets of spiro-connected azaacene dimers. Their geometry and electronic coupling are critically determined by a secondary linker, i.e. an etheno- and an ethano-bridge.The core fragment of the etheno-bridged dimer corresponds to a conformationally lo... |

A series of quinoxalinophenanthrophenazines (QPPs) with two-dimensional triptycene end-caps was synthesized from a triphenylene base ortho-diamine. UV/vis spectroscopy suggested the formation of dimers in solution which was further confirmed by MALDI-TIMS-TOF-MS and single crysta... |
