Popp, Dennis; Elbert, Sven Michael; Barwig, Chantal; Petry, Julian; Rominger, Frank; Mastalerz, Michael, 2023, "Palladium-Catalyzed Cyclization of a Pyryne Precursor to Higher Pyrenylenes [Data]", https://doi.org/10.11588/data/1TCKKG, heiDATA, V1
By palladium-catalyzed oligomerization reactions of pyrene-based o-trimethylsilyl triflates, larger cyclic pyrenylenes were formed with up to 10-membered rings as has been unambiguously characterized by SCXRD. Furthermore, the underlying reaction mechanism has been studied by qua... |

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... |

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... |

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... |
