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... |

Maier, Steffen, 2023, "Substituted Cyclopentannulated Tetraazapentacenes [data]", https://doi.org/10.11588/data/AUTKBW, heiDATA, V1
Brominated pentannulated dihydrotetraazapentacenes were prepared by gold- or palladium-catalyzed 5-endo-dig cyclization of TIPS-ethynylated dihydrotetraazaacenes (TIPS = triisopropylsilyl). Post-functionalization was demonstrated by Sonogashira alkynylation and Rosenmund-von Brau... |

Maier, Steffen, 2023, "Azaarenes: 13 Rings in a Row by Cyclopentannulation [data]", https://doi.org/10.11588/data/CSP7AW, heiDATA, V1
Cyclopentannulation was explored as a strategy to access large, stable azaarenes. Buchwald-Hartwig coupling of previously reported di- and tetrabrominated cyclopentannulated N,N'-dihydrotetraazapentacenes furnished stable azaarenes with up to 13 six-membered rings in a row and a... |

Wiesner, Thomas, 2022, "N-Acenoacenes: Synthesis and Solid-State Properties [Data]", https://doi.org/10.11588/data/645DDB, heiDATA, V1
Four N-acenoacenes were synthesized and analyzed for their optoelectronic properties and solid-state packings. Two of the regioisomeric acridinoacridines are TIPS-ethynylated, whereas the other pair are Boc- and triflate substituted derivatives. The two TIPS- ethynyldiazaacenoace... |
