Wiesner, Thomas, 2022, "N-Acenoacenes: Synthesis and Solid-State Properties [Data]", https://doi.org/10.11588/data/645DDB, heiDATA, V1
Four N-acenoacenes were synthesized and analyzed for their optoelectronic properties and solid-state packings. Two of the regioisomeric acridinoacridines are TIPS-ethynylated, whereas the other pair are Boc- and triflate substituted derivatives. The two TIPS- ethynyldiazaacenoace... |

Schroll, Moritz, 2022, "Methane cycling in a eutrophic lake characterised by multiple stable isotope and flux measurements [data]", https://doi.org/10.11588/data/MU3CON, heiDATA, V1, UNF:6:uMXNN9yPRjWKSRIzJA3uuA== [fileUNF]
Recent estimations demonstrate that methane (CH4) emissions from aquatic systems are responsible for up to half of global CH4 emissions. Lakes represent one of the largest CH4 sources, and emissions are predicted to increase due to global warming. However, there is a large uncert... |

Werner, Marius; Pampel, Julius; Pham, Truc Lam; Thomas, Franziska, 2022, "Late-Stage Functionalisation of Peptides on the Solid Phase by an Iodination-Substitution Approach [Research Data]", https://doi.org/10.11588/data/RG2NHY, heiDATA, V1
The functionalisation of peptides at a late synthesis stage holds great potential, for example, for the synthesis of peptide pharmaceuticals, fluorescent biosensors or peptidomimetics. Here we describe an on-resin iodination-substitution reaction sequence on homoserine that is al... |

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... |

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... |
