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... |

Hashmi, A. Stephen K.; Hüßler, Christopher; Kahle, Justin; Dietl, Martin C.; Krämer, Petra; Rominger, Frank; Rudolph, Matthias, 2024, "Facile two-step Synthesis of para-Dithienopyrazines [data]", https://doi.org/10.11588/data/14RXKL, heiDATA, V1
N-Heteropolycyclic compounds are valuable building blocks in organic electronic devices. In this work, a convenient route for the synthesis of para-dithienopyrazines from readily available starting materials is described. A cascade of nucleophilic aromatic substitution and subseq... |

Marty-Lombardi, Sebastián; Lu, Shiying; Ambroziak, Wojciech; Schrenk-Siemens, Katrin; Wang, Jialin; DePaoli-Roach, Anna A.; Hagenston, Anna M.; Wende, Hagen; Tappe-Theodor, Anke; Simonetti, Manuela; Bading, Hilmar; Okun, Jürgen G.; Kuner, Rohini; Fleming, Thomas; Siemens, Jan, 2024, "Neuron-astrocyte metabolic coupling facilitates spinal plasticity and maintenance of inflammatory pain [data]", https://doi.org/10.11588/data/AMDH7G, heiDATA, V1
Long-lasting pain stimuli can trigger maladaptive changes in the spinal cord, reminiscent of plasticity associated with memory formation. Metabolic coupling between astrocytes and neurons has been implicated in neuronal plasticity and memory formation in the CNS, but neither its... |

Ludwig, Philipp; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2024, "Stabilization of Acenes: “Geländer”-Pentacenes [data]", https://doi.org/10.11588/data/NITIKZ, heiDATA, V1
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... |

Stump, Annika; Voss, Andreas; Rummel, Jan, 2024, "The illusory certainty: Information repetition and impressions of truth enhance subjective confidence in validity judgments independently of the factual truth [Dataset]", https://doi.org/10.11588/data/WDQJWW, heiDATA, V1
People not only judge repeatedly perceived information as more likely being true (the so-called truth effect) they also tend to be more confident after judging the validity of repeated information. These phenomena are assumed to be caused by a higher subjective feeling of ease (i... |

Zeitter, Nico; Hippchen, Nikolai; Baur, Philipp; Unterreiner, Tamara; Freudenberg, Jan; Rominger, Frank; Bunz, Uwe, 2024, "Pentacene to Octacene: The Limit of Fourfold TIPS-Ethynylation [data]", https://doi.org/10.11588/data/DDJFGS, heiDATA, V1
Soluble acenes beyond hexacene are rare. Their sensitivity complicates isolation, purification and application in devices. To increase the stability of acenes, functionalization with trialkylsilylethynyl substituents prevents [4+4] dimerization and oxidation. At the same time suc... |

Schmidt, Martina; Hoheisel, Antje, 2024, "Six years of continuous CH4 mole fraction and δ13C-CH4 measurements in Heidelberg (Germany) [data]", https://doi.org/10.11588/data/OXKVW2, heiDATA, V1
δ13C-CH4 and the mole fraction of CH4 have been measured continuously since April 2014 using a cavity ring-down spectroscopy (CRDS) analyser in Heidelberg, Germany. This 6-year time series shows an increasing trend of (6.8 ± 0.3)ppb a−1 for the CH4 mole fraction between 2014 and... |

Weiser, Hannah; Ulrich, Veit; Winiwarter, Lukas; Esmorís, Alberto M.; Höfle, Bernhard, 2024, "Manually labeled terrestrial laser scanning point clouds of individual trees for leaf-wood separation", https://doi.org/10.11588/data/UUMEDI, heiDATA, V1, UNF:6:9U7BGTgjjsWd1GduT1qXjA== [fileUNF]
This dataset contains 11 terrestrial laser scanning (TLS) tree point clouds (in .LAZ format v1.4) of 7 different species, which have been manually labeled into leaf and wood points. The labels are contained in the Classification field (0 = wood, 1 = leaf). The point clouds have a... |
Siemssen, Tjaark; Maier, Andreas, 2024, "Ergänzungsmaterial zu: Rivers run and people may meander. Water body-oriented land use decisions in the Neuwied Basin during the Late Upper Palaeolithic and Late Palaeolithic", https://doi.org/10.11588/data/ZUJRXV, heiDATA, V1
Rivers are often seen to have played an important role for Palaeolithic hunter-gatherers as landmarks and resource location. While the former view regards rivers as passive guidelines or obstacles, the latter reduces them to their economic value. Both views, therefore, look at ge... |
