Recent Advances on the Applications of Luminescent Pb2+-Containing Metal–Organic Frameworks in White-Light Emission and Sensing

Abstract

Luminescent Pb2+-based metal–organic frameworks (MOFs) belong to a new class of multifunctional molecular materials with interesting luminescence properties and potential applications within a single crystalline phase. In this mini review, we present the recent advances that have been achieved in their applications as single-phase white-light emitting materials and chemosensors in the last decade. We focus on the trends in the modification of their structures and luminescence by various bridging ligands, and subsequently their multifunctional applications, which may affect the future development of the field.

Multifunctional Luminescent Sensor Based on the Pb2+ Complex Containing a Tetrazolato Ligand

“…In our recent communication, we have reported two luminescent porous Pb 2+ coordination polymers based on the tetrazolate-containing ligands, including 1D cage-containing chains and 1D double helical chains with 1D channels (Figure ). Both compounds show weak emissions at room temperature, which are ascribed to the metal-centered (MC) origin associated with the s and p orbitals of Pb 2+ . Interestingly, these polymers can take up various metal ions and exhibit different luminescence responses depending on the metal ions .…”

“… Both compounds show weak emissions at room temperature, which are ascribed to the metal-centered (MC) origin associated with the s and p orbitals of Pb 2+ . Interestingly, these polymers can take up various metal ions and exhibit different luminescence responses depending on the metal ions . In order to further enhance their luminescence properties and then their potential applications, a series of new tetrazole-containing polypyridyl ligands ( L 1 - L 4 , Figure ) are employed.…”
