Abstract:Poly‐aromatic systems that contain quinodimethyl (QDM) units are appealing for several photonic and spintronic applications owing to the unique electronic structure, aromaticity, and spin state(s) of the QDM ring. Herein, we report the synthesis and characterization of novel QDM‐based chromophores 1–3, which exhibit unique photo‐excited behavior and aromaticity. Extending the aromatic core with a biphenyl/phenanthryl‐ and a pyrrolo‐fragment led to reducing the optoelectronic bandgap and modulating the photophy… Show more
