The SFB 1249 is an interdisciplinary Collaborative Research Centre at Heidelberg University with project partners at the Karlsruhe Institute of Technology (KIT), MPI for Solid State Research in Stuttgart, University of Kassel and the Heidelberg Institute for Theoretical Studies (HITS). It is funded by the German Research Foundation (DFG).

The aim of this SFB is the development of novel organic functional materials with specifically tailored electronic properties and their application as photoactive components and organic semiconductors. We focus on the molecular class of N-heteropolycycles, which provide a wide range of tunable structures. Research areas include Synthesis (A), Theory and Structure (B), and Material and Function (C).

Marder; Jan Freudenberg; Uwe H. F. Bunz, 2023, "The Radical Anion and Dianion of Benzo[3,4]cyclobuta[1,2-b]phenazine [NMR data]", https://doi.org/10.11588/data/JCO0E4, heiDATA, V1
The data set includes the NMR data for the puplication: "The Radical Anion and Dianion of Benzo[3,4]cyclobuta[1,2-b]phenazine". We present the reduction of two azaarenes, featuring a single cyclobutadiene unit, to their radical anions and dianions. The reduced species were prepar...
Substituted Cyclopentannulated Tetraazapentacenes [data]
Feb 6, 2023 - Bunz Group
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...
Chirale polyzyklische aromatische Kohlenwasserstoffe mit Affensattel-Topologie [Data]

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...
Cyclopentannulated Dihydrotetraazapentacenes [Data]
Feb 24, 2022 - Bunz Group
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...
