本研究通过铃木-宫浦偶联和肖尔反应,成功合成了一种具有扭曲结构的硫杂石墨烯纳米条带分子。将噻吩单元选择性地氧化为砜基团,能够显著调控该分子的光物理和电化学性质。进一步采用密度泛函理论计算阐明了硫杂石墨烯纳米条带分子及其氧化物的电子激发机制与芳香性特征。本工作为制备具有可调电子性质的硫掺杂石墨烯纳米带提供了一条简洁高效的合成路线。

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.

Key words: Graphene nanoribbons, sulfur doping, electrochemical synthesis
