“…[32][33][34] Owing to their unique structures and various functional properties, including excellent semiconductor properties and catalytic activities, MPc derivatives have been widely used in various elds including catalysis, sensors, and photodynamic therapy. [35][36][37][38][39][40][41][42] Due to its redox activity, catalytic activity, and carrier transport ability result from the extended p-system, MPc complexes have been used as the linking units in 2D MOFs, which show good stability, conductivity, redox activity, and electrocatalytic activity. [43][44][45] Here, we developed a novel electrochemical sensor based on an iron phthalocyanine (FePc) MOF for the sensitive detection of vanillin.…”
