Turning on the biradical state of tetracyano-perylene and quaterrylenequinodimethanes by incorporation of additional thiophene rings by Zeng, Zebing, Lee, Sangsu, Zafra, José L., Ishida, Masatoshi, Bao, Nina, Webster, Richard David, López Navarrete, Juan T., Ding, Jun, Casado, Juan, Kim, Dongho, Wu, Jishan

“…In this work, we found that after incorporation of two additional thiophene rings into the closed-shell tetracyano-perylene (Per-CN) and quaterrylenequinodimethanes (QR-CN), the obtained new quinoidal compounds QDTP and QDTQ became a singlet biradical in the ground state due to the recovery of aromaticity of the thiophene rings in the biradical form and additional steric repulsion between the thiophene rings and the rylene unit. …”
