Uhrmacher, Fabian; Elbert, Sven Michael; Rominger, Frank; Mastalerz, Michael, 2022, "Synthesis of Large [2+3] Salicylimine Cages with Embedded Metal-Salphen Units [Data]", https://doi.org/10.11588/data/LOR2JH, heiDATA, V1
Shape-persistent trinuclear Ni(II)- and Pt(II)-cage compounds with large cavities have been synthesized by using bissalicylaldehyde struts that contain the metal salphen units already. The Pt(II) derivative was investigated by single crystal X-ray diffraction. |

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... |

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... |

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... |

Benke, Bahiru P.; Kirschbaum, Tobias; Graf, Jürgen; Gross, Jürgen; Mastalerz, Michael, 2022, "Dimeric and Trimeric Catenation of Giant Chiral [8+12] Imine Cubes Driven by Weak Supramolecular Interactions [Data]", https://doi.org/10.11588/data/HI9BJD, heiDATA, V1
Mechanically interlocked structures, such as catenanes or rotaxanes are fascinating synthetic targets and some are used for molecular switches and machines. Today, the vast majority of catenated structures are built upon macrocycles and only a very few examples of three-dimension... |

Reinhard, Dennis; Rominger, Frank; Mastalerz, Michael, 2022, "Desymmetrization Strategy to Achieve Triptycene-Based 3,6-Dimethoxytriphenylenes via Oxidative Cyclodehydrogenation [Data]", https://doi.org/10.11588/data/OH6757, heiDATA, V1
To achieve a highly symmetric triptycene based hexamethoxytriphenylene in high yield of 97 %, a less symmetric triptycene (C3v) is necessary as precursor for cyclodehydrogenative Scholl-type oxidation, by taking into account the regioselectivity of the C-C bond formation controll... |

Yang, Xuan; Rominger, Frank; Mastalerz, Michael, 2022, "Contorted Heteroannulated Tetraareno[a,d,j,m]coronenes [Data]", https://doi.org/10.11588/data/RYUGT2, heiDATA, V1
Cata-condensed heteroannulated tetraarenocoronenes with C2h symmetry have been obtained from three doubly brominated diarenoperylenes. X-ray diffraction showed that the coronenes mostly adopt S-shaped contorted π-planes. The large variety of fused rings in the coronenes′ core all... |

Kirschbaum, Tobias, 2022, "Chirale polyzyklische aromatische Kohlenwasserstoffe mit Affensattel-Topologie [Data]", https://doi.org/10.11588/data/SHVINO, heiDATA, V1
In this thesis, the first chiral polycyclic aromatic hydrocarbon (PAH) with a monkey saddle topology is presented. Starting from a truxene building block that is readily preparatively accessible, the monkey saddle PAH could easily be obtained in three steps. By using additional f... |

Yang, Xuan; Rominger, Frank; Mastalerz, Michael, 2022, "Benzo-Fused Perylene Oligomers with up to 13 Linearly Annulated Rings [Data]", https://doi.org/10.11588/data/2TX0VD, heiDATA, V1
The longer acenes with more than six linearly fused six-membered rings are still fascinating chemists and physicists because of their unique photophysical properties and their high potential for organic electronics applications. Unfortunately, with increasing size (seven and more... |
