Chem. Sci., 2024, 15,10519-10528DOI: 10.1039/D4SC02116A, Edge Article Open Access &nbsp This article is licensed under a Creative Commons Attribution-NonCommercial 3.0 Unported Licence.Qing Jiang, Hui Tang, Yuchen Peng, Zhenni Hu, Wangdong ZengTwo new quinodimethane-embedded expanded helicenes were synthesized, showing an open-shell singlet diradical character. Moreover, the effect of electron transfer on their backbones and aromaticity was also studied.The content of this RSS Feed (c) The Royal Society of Chemistry
