Werner, Marius; Pampel, Julius; Pham, Truc Lam; Thomas, Franziska, 2022, "Late-Stage Functionalisation of Peptides on the Solid Phase by an Iodination-Substitution Approach [Research Data]", https://doi.org/10.11588/data/RG2NHY, heiDATA, V1
The functionalisation of peptides at a late synthesis stage holds great potential, for example, for the synthesis of peptide pharmaceuticals, fluorescent biosensors or peptidomimetics. Here we describe an on-resin iodination-substitution reaction sequence on homoserine that is al... |

Benke, Bahiru P.; Kirschbaum, Tobias; Graf, Jürgen; Gross, Jürgen; Mastalerz, Michael, 2022, "Dimeric and Trimeric Catenation of Giant Chiral [8+12] Imine Cubes Driven by Weak Supramolecular Interactions [Data]", https://doi.org/10.11588/data/HI9BJD, heiDATA, V1
Mechanically interlocked structures, such as catenanes or rotaxanes are fascinating synthetic targets and some are used for molecular switches and machines. Today, the vast majority of catenated structures are built upon macrocycles and only a very few examples of three-dimension... |

Kirschbaum, Tobias, 2022, "Chirale polyzyklische aromatische Kohlenwasserstoffe mit Affensattel-Topologie [Data]", https://doi.org/10.11588/data/SHVINO, heiDATA, V1
In this thesis, the first chiral polycyclic aromatic hydrocarbon (PAH) with a monkey saddle topology is presented. Starting from a truxene building block that is readily preparatively accessible, the monkey saddle PAH could easily be obtained in three steps. By using additional f... |

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... |

Hsu, Li-Yun; Mainik, Philipp; Münchinger, Alexander; Lindenthal, Sebastian; Spratte, Tobias; Welle, Alexander; Zaumseil, Jana; Selhuber-Unkel, Christine; Wegener, Martin; Blasco, Eva, 2022, "A Facile Approach for 4D Microprinting of Multi-Photoresponsive Actuators [data]", https://doi.org/10.11588/data/MR5H4A, heiDATA, V1
For microscale 4D photoresponsive actuators, light is crucial in two ways. First, the underlying additive manufacturing techniques rely on photopolymerization processes triggered by the absorption of light. Second, the absorption of light serves as the actuation stimulus. The two... |

Wiesner, Thomas; Wu, Zhu; Han, Jie; Ji, Lei; Friedrich, Alexandra; Krummenacher, Ivo; Moos, Michael; Lambert, Christoph; Braunschweig, Holger; Rudin, Benjamin; Reiss, Hilmar; Tverskoy, Olena; Rominger, Frank; Dreuw, Andreas; Marder, Todd; Freudenberg, Jan; Bunz, Uwe, 2022, "The Radical Anion, Dianion and Electron Transport Properties of Tetraiodo-Tetraazapentacene [Data]", https://doi.org/10.11588/data/S0KS2I, heiDATA, V1
Tetraiodotetraazapentacene I4TAP , the last missing derivative in the series of halogenated silylated tetraazapentacenes, was synthesized via condensation chemistry from a TIPS-ethynylated diaminobenzothiadiazol in three steps. Single and double reduction furnished its air-stable... |
Pham, Truc Lam; Zilke, Jennifer; Müller, Christine Charlotte; Thomas, Franziska, 2022, "The CSY-protecting group in the microwave-assisted synthesis of aggregation-prone peptides [Research Data]", https://doi.org/10.11588/data/ECKCUY, heiDATA, V1
This report describes the application of cyanosulfurylide (CSY)-protected aspartatic acid building blocks in microwave-assisted synthesis of aggregation-prone protein domains. We present a synthesis of Fmoc-Asp(CSY)-OH on a multigram scale, as well as procedures for the microwave... |

Maier, Steffen; Heckershoff, Robin; Wurm, Thomas; Biegger, Philipp; Brödner, Kerstin; Krämer, Petra; Hoffmann, Marvin; Eberle, Lukas; Stein, Jana; Rominger, Frank; Rudolph, Matthias; Freudenberg, Jan; Dreuw, Andreas; Hashmi, Stephen; Bunz, Uwe, 2022, "Cyclopentannulated Dihydrotetraazapentacenes [Data]", https://doi.org/10.11588/data/PZGMSS, heiDATA, V1
The transition-metal catalyzed cyclization of bissilylethynylated N,N’-dihydro¬tetra¬aza¬pentacene (TIPS-TAP-H2) into bissilylated cyclo¬penta¬[fg,qr]¬pentacenes is reported. Depending on the catalyst either none, one or two silyl groups migrate and change their positions in the... |
Pham, Truc Lam; Kovermann, Michael; Thomas, Franziska, 2022, "Switchable Zinc (II)-Responsive Globular β-Sheet Peptide [Research Data]", https://doi.org/10.11588/data/HV4MJW, heiDATA, V1
The natural function of many proteins depends on their ability to switch their conformation driven by environmental changes. In this work, we present a small, monomeric β-sheet peptide that switches between a molten globule and a folded state through Zn(II) binding. The solvent-e... |

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... |
