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... |

Roß, Lisa; Reitemeier, Julius; Ghalami, Farhad; Zhang, Wen-Shan; Gross, Jürgen H.; Rominger, Frank; Elbert, Sven M.; Schröder, Rasmus; Elstner, Marcus; Mastalerz, Michael, 2023, "Two Dimensional Triptycene End-Capping and Its Influence on the Self-Assembly of Quinoxalinophenanthrophenazines [Data]", https://doi.org/10.11588/data/W3KWEJ, heiDATA, V1
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... |

Lauer, Jochen C.; Bhat, Avinash S.; Barwig, Chantal; Rominger, Frank; Mastalerz, Michael, 2022, "[2+3] Amide Cages by Oxidation of [2+3] Imine Cages - Revisiting Molecular Hosts for Efficient Nitrate Binding [Data]", https://doi.org/10.11588/data/HWLKZT, heiDATA, V1
The pollution of groundwater with nitrate is a serious issue because nitrate can cause several diseases such as methemoglobinemia or cancer. Therefore, selective removal of nitrate by efficient binding to supramolecular hosts is highly desired. Here we describe how to make [2+3]... |
