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; Elbert, Sven Michael; Rominger, Frank; Mastalerz, Michael, 2022, "A Series of Soluble Thieno-fused Coronene Nanoribbons of Precise Lengths [Data]", https://doi.org/10.11588/data/30AOAT, heiDATA, V1
Among graphene nanoribbons (GNRs), reports on coronene-based GNRs were very rare, despite the unique optoelectronic properties of coronene. Herein, the synthesis of a series of structurally precise and soluble thieno-fused coronene nanoribbons (CR-1 to CR-4) with up to four coron... |

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... |

Maier, Steffen, 2022, "A Stable Hexaazaoctacene Cruciform σ-Dimer [Data]", https://doi.org/10.11588/data/FABJEI, heiDATA, V1
Buchwald‐Hartwig coupling of a triisopropylsilyl (TIPS)‐ethynylated dibromo‐N,N'‐dihydrotetraazapentacene with 1,4‐bis(TIPS‐ethynyl)‐2,3‐diaminonaphthalene furnishes a dihydrohexaazaoctacene. Its oxidation with MnO2 results in a 7,7'‐bi(hexaazaoctacenyl). In addition to eight TIP... |

W.; Hermerschmidt, Felix, 2022, "Crosslinking Super Yellow to produce Super OLEDs: Crosslinking with Azides Enables Improved Performance [Data]", https://doi.org/10.11588/data/K7GEM8, heiDATA, V1
An increasing number of organic light-emitting diodes (OLEDs) is nowadays based on the use of polymers as the emissive material. For this material class in particular, solution-processing of the OLEDs has gained traction in both research and industry. However, in order to access... |

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... |
