Ehjeij, Daniel; Hengge, Michael; Hänsch, Paul; Benneckendorf, Frank S.; Freudenberg, Jan; Bunz, Uwe H. F. Bunz; Müllen, Klaus; List-Kratochvil, Emil J. 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... |

Zeitter, Nico; Hippchen, Nikolai; Maier, Steffen; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F.; Dreuw, A, 2022, "Persistent Ambipolar Heptacenes and Their Redox Species [Data]", https://doi.org/10.11588/data/CVD7WF, heiDATA, V1
Research Data associated with the related publication. Sixfold TIPS-ethynylation combined with fourfold bromination of the armchair edges furnishes a long-lived, soluble heptacene; π-extension via Stille coupling accesses a persistent tetrabenzononacene. Both types of acenes were... |

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, "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... |

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... |

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... |

Lauer, Jochen C.; Kohl, Bernd; Rominger, Frank; Mastalerz, Michael, 2022, "A Hexagonal Shape-Persistent Nanobelt of Elongated Rhombic Symmetry with Orthogonal π-Planes by a One-Pot Reaction [Data]", https://doi.org/10.11588/data/EBY4AN, heiDATA, V1
Triptycenes with their predefined D3h-symmetry are excellent molecular building blocks to construct shape-persistent nanobelts having π-orbitals orthogonal to the ring plane. However, up to now, there are only a very few examples of fused and rigid iptycene nanobelts synthesized... |
