Roß, Lisa; Reitemeier, Julius; Ghalami, Farhad; Zhang, Wen-Shan; Gross, Jürgen H.; Rominger, Frank; Elbert, Sven M.; Schröder, Rasmus; Elstner, Marcus; Mastalerz, Michael, 2023, "Two Dimensional Triptycene End-Capping and Its Influence on the Self-Assembly of Quinoxalinophenanthrophenazines [Data]", https://doi.org/10.11588/data/W3KWEJ, heiDATA, V1
A series of quinoxalinophenanthrophenazines (QPPs) with two-dimensional triptycene end-caps was synthesized from a triphenylene base ortho-diamine. UV/vis spectroscopy suggested the formation of dimers in solution which was further confirmed by MALDI-TIMS-TOF-MS and single crysta... |

Eichelmann, Robert; Ballmann, Joachim; Gade, Lutz H., 2024, "Tetraazacoronenes and Their Dimers, Trimers and Tetramers [data]", https://doi.org/10.11588/data/ZT3AHN, heiDATA, V1
Tetraazacoronenes were synthesized from bay-functionalized tetraazaperylenes by Zr-mediated cyclization and four-fold Suzuki–Miyaura cross coupling. In the Zr-mediated approach, an η4-cyclobutadiene-zirconium(IV) complex was isolated as an intermediate to cyclobutene-annulated de... |
