Klee, Pia S.; Vazquez-Martel, Clara; Florido Martins, Lilliana; Blasco, Eva, 2023, "Designing Sustainable Polymers: Lactate Esters for 3D Printing and Upcycling [data]", https://doi.org/10.11588/data/NUIXMG, heiDATA, V1
The search for sustainable polymer systems is key to tackling the current climate crisis. However, the use of bio-based polymers does not suffice to achieve this goal. Additionally, new chemical approaches enabling the re- or upcycling of polymer materials need to be explored. He... |

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... |

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... |

Fuchs, Kathleen; Dr. Rivero, Samara M.; Weidlich, Anna; Dr. Rominger, Frank; Israel, Noel; Dr. Popov, Alexey A.; Prof. Dreuw, Andreas; Dr. Freudenberg, Jan; Prof. Casado, Juan; Prof. Bunz, Uwe, 2023, "Dimerization of a Reactive Azaacene Diradical: Synthesis of a Covalent Azaacene Cage [Data]", https://doi.org/10.11588/data/QO118B, heiDATA, V1
Two series of regioisomeric dicyanomethylene substituted dithienodiazatetracenes with formal para- or ortho- quinodimethane subunits were synthesized and characterized. Whereas the para-isomers (p-n, diradical index y0=0.01) are stable and isolable, the ortho-isomer (y0=0.98) dim... |

Yang, Xuan; Brückner, Margit; Rominger, Frank; Kirschbaum, Tobias; Mastalerz, Michael, 2024, "Dispersion-Driven Formation of Chiral Twisted PAH Double Helices [Data]", https://doi.org/10.11588/data/BRM2DI, heiDATA, V1
Molecular double helices are ubiquitous in nature and have also been generated artificially. These are usually based on helical ribbons. Here, a new type of double helices based on twisted ribbons is introduced. The monomeric strands are polycyclic aromatic hydrocarbons of variou... |

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... |
