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... |

Wang, Xubin; Kohl, Bernd; Rominger, Frank; Elbert, Sven Michael; Mastalerz, Michael, 2022, "A Triptycene-Based Enantiopure Bis(Diazadibenzoanthracene) by a Chirality-Assisted Synthesis Approach [Data]", https://doi.org/10.11588/data/46LINE, heiDATA, V1
By applying a chirality-assisted synthesis (CAS)approach enantiopure diaminodibromotriptycenes were converted to rigid chiral helical diazadibenzoanthracenes, which show besides pronounced Cotton effects in circular dichroism spectra higher photoluminescence quantum yields as com... |

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... |

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... |

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, "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... |

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. |

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... |
