Gvaramia, David; Fisch, Philipp; Flégeau, Killian; Huber, Lena; Kern, Johann; Jakob, Yvonne; Hirsch, Daniela; Rotter, Nicole, 2024, "Evaluation of Bioprinted Autologous Cartilage Grafts in an Immunocompetent Rabbit Model [data]", https://doi.org/10.11588/data/0BQTPT, heiDATA, V1
The current gold standard of auricular reconstruction involves a highly time-consuming manual graft assembly from autologous costal cartilage. The intervention may require multiple surgical procedures and lead to donor-site morbidity, while the outcome is highly dependent on indi... |

Ehjeij, Daniel; Rominger, Frank; Bunz, Uwe; Freudenberg, Jan; Müllen, Klaus, 2024, "Thermolysis of Biphenylene toward Cyclo-ortho-phenylenes [data]", https://doi.org/10.11588/data/AYVNYK, heiDATA, V1
The solvent and catalyst free thermolysis of biphenylenes at 350 °C furnishes [n]cyclo-ortho-phenylenes ([n]COPs, n=4–10) in one step and in high yields. At 400 °C biphenylene dimerizes into tetraphenylene, but lower reaction temperatures produce cyclooligomers. If suitably subst... |

Catt, Samantha; Hackner, Maximillian; Spatz, Joachim P.; Blasco, Eva, 2024, "Macromolecular Engineering: From Precise Macromolecular Inks to 3D Printed Microstructures [data]", https://doi.org/10.11588/data/T2SJZC, heiDATA, V1
Macromolecules with complex, defined structures exist in nature but rarely is this degree of control afforded in synthetic macromolecules. Sequence-defined approaches provide a solution for precise control of the primary macromolecular structure. Despite a growing interest, very... |

Eichelmann, Robert; Monti, Joël; Hsu, Li-Yun; Kröger, Finn; Ballmann, Joachim; Blasco, Eva; Gade, Lutz H., 2024, "Two-Photon Microprinting of 3D Emissive Structures Using Tetraazaperylene-Derived Fluorophores [data]", https://doi.org/10.11588/data/C6UIWL, heiDATA, V1
The application of a new class of fluorophores based on a twisted tetraazaperylene core in the fabrication of emissive organic 3D microstructures has been investigated. The synthesis of a series of tetraazaperyleneamines and their corresponding octaazaperopyrenedioxides (OAPPDOs)... |

Eichelmann, Robert; Rippel, Daniel; Ballmann, Joachim; Gade, Lutz H., 2024, "Zipping up Tetraazaperylene: Synthesis of Tetraazacoronenes via Double Coupling in the Bay Positions [data]", https://doi.org/10.11588/data/HIERR9, heiDATA, V1
Substituted tetraazacoronene fluorophores have been obtained selectively by double Suzuki–Miyaura cross coupling of symmetrically substituted 1,2-bis(pinacolatoboryl)alkenes with a bay-substituted octaazaperopyrenedioxide (OAPPDO). Subsequent Scholl reaction of the dimethoxypheny... |

Eichelmann, Robert; Jeudy, Pierre; Schneider, Lars; Zerhoch, Jonathan; Mayer, Paula R.; Ballmann, Joachim; Deschler, Felix; Gade, Lutz H., 2024, "Chiral Bay-Alkynylated Tetraazaperylenes: Photophysics and Chiroptical Properties", https://doi.org/10.11588/data/PGSVXO, heiDATA, V1
Fully bay-alkynylated octaazaperopyrene dioxide (OAPPDO) derivatives were accessible through Stille cross coupling reaction of the corresponding bay-chlorinated derivatives. This steric congestion of the bay area led to helically chiral fluorophores, and chiral resolution of two... |

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... |

Zong, Wansheng; Hippchen, Nikolai; Nico, Zeitter; Maier, Steffen; Philipp, Ludwig; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2024, "Stable Azaheptacenes", https://doi.org/10.11588/data/P9AVCU, heiDATA, V1
we have developed a novel access to stable azaheptacenes and investigated both their (air-stable) radical anions as well as dianions. The two azaheptacenes are significantly more stable than reported examples. We identified their structure through NMR, IR, MS and X-ray crystallog... |

We report soluble tetrakis-biphenyl substituted pentacenes comprised of sp2 carbons and synthesized from pentacene-5,7,12,14-tetraone. Intramolecular Yamamoto coupling of two tetrakis(chlorobiphenylyl)pentacenes yields helical, doubly wrapped pentacenes, in which the quaterphenyl... |
