Keck, Christoph; Rominger, Frank; Mastalerz, Michael, 2024, "Synthesis of Chiral Pyrene-Based 1,4-Dithiins [Data]", https://doi.org/10.11588/data/NCRUAV, heiDATA, V1
The 1,4-dithiin motif is known for its reversible redox properties to generate radical cations and diradical dications and thus is interesting for organic electronic applications. However, examples where this motif is embedded into chiral larger fused aromatic compounds is very r... |

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... |

Vallejo Orti, Miguel; Anders, Katharina; Ajali, Oliubikum; Bubenzer, Olaf; Höfle, Bernhard, 2024, "Integrating VGI contributions for gully mapping using Kalman filter and machine learning", https://doi.org/10.11588/data/UHSQG0, heiDATA, V1, UNF:6:dbfZe/C8CmWXcBEZJg2RPw== [fileUNF]
The codes and datsets included are related to experiments and results conducted to integrate different lines digitized by volunteers using Kalman filter with changing amount of input lines. Three approaches are included: i) Kalman filtering integration to investigate the role of... |
Pham, Truc Lam; Fazliev, Sunnatullo; Baur, Philipp; Comba, Peter; Thomas, Franziska, 2024, "An Engineered β-Hairpin Peptide Forming Thermostable Complexes with ZnII, NiII, and CuII through a His3 Site [Research Data]", https://doi.org/10.11588/data/SIESG0, heiDATA, V1
The three-dimensional structure of a peptide, which determines its function, can denature at elevated temperatures, in the presence of chaotropic reagents, or in organic solvents. These factors limit the applicability of peptides. Herein, we present an engineered β-hairpin peptid... |
Illig, Maja; Jahnke, Kevin; Weise, Lukas P.; Scheffold, Marlene; Mersdorf, Ulrike; Drechsler, Hauke; Zhang, Yixin; Diez, Stefan; Kierfeld, Jan; Göpfrich, Kerstin, 2024, "Triggered contraction of self-assembled micron-scale DNA nanotube rings [Research Data]", https://doi.org/10.11588/data/ADYUNN, heiDATA, V1, UNF:6:AJdXI51lTUqvs4V/XCVPZQ== [fileUNF]
Contractile rings formed from cytoskeletal filaments mediate the division of cells. Ring formation is induced by specific crosslinkers, while contraction is typically associated with motor protein activity. Here, we engineer DNA nanotubes as mimics of cytoskeletal filaments and a... |

Taale, Mohammadreza, 2024, "A Minimalistic, Synthetic Cell-Inspired Metamaterial for Enabling Reversible Strain-Stiffening [data]", https://doi.org/10.11588/data/MNMLVX, heiDATA, V1
Strain-stiffening, i.e. the nonlinear stiffening of a material in response to a strain, is an intrinsic feature of many biological systems, including skin, blood vessels, and single cells. To avoid a mismatch in mechanical properties, synthetic materials in contact with such biol... |
