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... |

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... |
Zong, Wansheng; Hippchen, Nikolai; Dittmar, Benedikt; Elter, Maximilian; Ludwig, Philipp; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2024, "Halogenated Phenazinothiadiazoles: Electron Transporting Materials [data]", https://doi.org/10.11588/data/PKX5CI, heiDATA, V1, UNF:6:M6UVaar224tmBy3Sj1o9jg== [fileUNF]
Triisopropylsilyl-(TIPS)-alkynylated phenazinothiadiazoles were prepared by the condensation of halogenated ortho-quinones and TIPS-alkynylated 5,6-diamino-2,1,3-benzothiadiazole with different combinations of halogen substituents. The compounds pack in brickwall motif of head-to... |

Ahrens, Lukas; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2023, "Etheno-bridged Azaacene Spiro Dimers [data]", https://doi.org/10.11588/data/L8NDRO, heiDATA, V1
We present the synthesis of two sets of spiro-connected azaacene dimers. Their geometry and electronic coupling are critically determined by a secondary linker, i.e. an etheno- and an ethano-bridge.The core fragment of the etheno-bridged dimer corresponds to a conformationally lo... |
