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... |

F, 2023, "Hexakis-TIPS-Alkynylated Nonacenes: Persistent and Processible [data]", https://doi.org/10.11588/data/TFFFN4, heiDATA, V1
We prepared and characterized (UV-vis, epr, X-ray) four substituted nonacenes. They are the most stable and soluble nonacenes to date – due to six strategically placed triisopropylsilyl (TIPS)-ethynyl groups. They are stable for several weeks in the solid state. In dilute solutio... |
