Abstract:Lead ion (Pb2+) is a high‐hazardously heavy metal ion in surroundings that even ppb level can cause mental decline and behavioral difficulties especially in children. However, the recognition and detection of Pb2+ are still challenging. Here, a high selective and ultra‐sensitive chemiluminescence (CL) method was established based on the substitution mechanism between Pb2+ and the metal–organic framework – Cu‐MOF‐74. Pb2+ can specifically substitute Cu active sites in Cu‐MOF‐74 and released Cu sites, strongly a… Show more
