%X 共价有机框架(Covalent Organic Frameworks, COFs)具有高比表面积、结构可设计以及易功能化修饰等特性。以COFs为前驱体&#65292;通过直接煅烧制备的碳材料不仅具有高导电性&#65292;还能保留多孔结构和杂原子掺杂特性&#65292;显著提升材料的比表面积和催化活性。将COFs衍生碳材料用于构建电化学传感器&#65292;能够增强其对待测物的吸附和传质作用&#65292;提高传感性能。在本项研究中&#65292;以含有丰富氮元素的COF<sub>T</sub><sub>p</sub><sub>Pa</sub>为前驱体&#65292;成功制备了具有多孔结构的氮掺杂碳材料(NPC)。并采用循环伏安法(CV)、交流阻抗法(EIS)、差分脉冲伏安法(DPV)等一系列电化学检测技术&#65292;对使用NPC材料构建的对乙酰氨基酚(Acetaminophen, AP)传感器的性能进行了评估。NPC/GCE电极在进行电化学检测时对AP表现出良好的响应效果&#65292;经过一系列测试证明了其所构建的传感器具有优异的重复性、重现性、抗干扰等能力。<br>Covalent Organic Frameworks (COFs) exhibit remarkable properties, including a high specific surface area, a designable structure, and ease of functional modification. When COFs are employed as precursors for direct calcination, the resulting carbon materials not only possess high electrical conductivity but also retain their porous structure and heteroatom-doping features. This significantly enhances the specific surface area and catalytic activity of the materials. The utilization of COF-derived carbon materials in the fabrication of electrochemical sensors can facilitate the adsorption and mass transfer of analytes, thereby improving the sensing performance. In this study, nitrogen-doped carbon materials (NPC) with porous structure were successfully prepared using nitrogen-rich COF<sub>TpPa</sub> as a precursor. A range of electrochemical detection techniques, such as cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and differential pulse voltammetry (DPV), were employed to evaluate the performance of the acetaminophen (AP) sensor fabricated with NPC materials. During electrochemical detection, the NPC/GCE electrode demonstrated a favorable response to AP. A series of tests confirmed that the sensor exhibits excellent repeatability, reproducibility, and anti-interference capabilities.
