摘要

共价有机骨架具有比表面积大、孔隙丰富、稳定性好等优点，在构建电化学适体传感器领域具有广阔的应用前景。结晶度（即有序度）直接关系到多孔框架的结构特征，并影响其传感性能。然而，很少有报道关注结晶度对电催化适体感应性能的影响。本研究开发了不同结晶度的卟啉铜基COFs，用于制备青霉素的电化学感应传感器。研究结果表明，高度有序的COF具有更高的比表面积和有序的孔隙，可以显著提高传感性能。图形抽象

Adjustable crystallinity of covalent organic frameworks for electrochemical aptasensing of penicillin

Covalent organic frameworks (COFs) show a great potential application in the field of constructing electrochemical aptasensors due to their high specific surface area, abundant pores, and good stability. Crystallinity (i.e., orderliness) is directly related to the structural characteristics of porous frameworks and affects their sensing performance. However, few reports focus on the influence of crystallinity on electrocatalytic aptasensing performance. This work develops copper porphyrin-based COFs with different crystallinity to fabricate electrochemical aptasensors for detecting penicillin. The research results indicate that highly ordered COF has higher specific surface area and ordered pores, which can significantly improve sensing performance.
