In this study, a twisted sulfur-doped graphene nanoribbon (GNR) was successfully synthesized via a sequential Suzuki-Miyaura coupling and Scholl reaction. Oxidation of the incorporated thiophene units to sulfone groups was found to be a highly effective molecular engineering strategy, significantly modulating the photophysical and electrochemical properties of the nanoribbon. Density functional theory (DFT) calculations were employed to elucidate the underlying excited-state dynamics and aromatic characteristics. This work establishes a robust and efficient synthetic route for the preparation of sulfur-doped GNRs with precisely tailored electronic properties.
