Nonplanar Heterocyclic Electron Acceptor Molecules for Organic Electronics (A04)

• Subject Area: Organic Molecular Chemistry - Synthesis and Characterisation
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 281029004

The established motif of triptycene endcapping as crystal engineering synthon will be extended to new fused heteroaromatics as well as investigated for their potential to form charge-transfer crystals. In this respect, aza-derivatives of benzothienobenzothiophene will be synthesized. Furthermore, N-heterocyclic analogues of negatively curved structures, such as the hexabenzoovalene or a monkey saddle PAH will be explored. Last aspect of this project are N-heterocyclic systems with (multi-)radical open-shell character. Structure-property relationships of all new compounds will be theoretically and physically investigated by collaborations within this SFB.
