Abstract

Carbenes are divalent carbon species that have attracted significant research interest due to their ability to form two new bonds and their potential applications as ligands in catalysis and in the development of magnetic materials. In this study, we report singlet ground-state diarylcarbenes, embedded within a unique curved π-conjugated cycloparaphenylene (CPP) framework and composed solely of carbon and hydrogen atoms. We also examined the Möbius and Hückel aromaticity of these CPP-embedded carbenes.
