Stable Azaheptacenes

we have developed a novel access to stable azaheptacenes and investigated both their (air-stable) radical anions as well as dianions. The two azaheptacenes are significantly more stable than reported examples. We identified their structure through NMR, IR, MS and X-ray crystallography, and evaluated their stability through UV-Vis characterization. The raw-data (NMR, IR, UV-Vis, MS, CV and EPR spectra) concerning the intermediates and final products are uploaded to the dataset.
