“…By the rational design of metal ions and ligands in the complex structure, multiresponsive MOFs can be generated with their optical properties tuned by several stimuli. For example, Wang et al reported a two dimensional lead (II) based metal-organic framework assembly that is able to tune its luminescent properties upon temperature and nitroaromatic compounds-picric acid [72]. The MOF was composed of 5-aminonicotinic acid as a ligand and Pd (II) as a coordination metal synthesized by the solvothermal method.…”

Metal-organic framework (MOF) based stimuli-responsive polymers (coordination polymers) exhibit reversible phase-transition behavior and demonstrate attractive properties that are capable of altering physical and/or chemical properties upon exposure to external stimuli, including pH, temperature, ions, etc., in a dynamic fashion. Thus, their conformational change can be imitated by the adsorption/desorption of target analytes (guest molecules), temperature or pressure changes, and electromagnetic field manipulation. MOF-based stimuli responsive polymers have received great attention due to their advanced optical properties and variety of applications. Herein, we summarized some recent progress on MOF-based stimuli-responsive polymers (SRPs) classified by physical and chemical responsiveness, including temperature, pressure, electricity, pH, metal ions, gases, alcohol and multi-targets.

“…33 was found to be a heterogeneous catalyst for Knoevenagel condensation reaction and exhibited no sensing properties, while 34 was found to be a luminescence sensor for Fe 3+ with good recyclability (Zhang et al, 2019). Recently, a 2D framework [PbL 18 (NO 3 )] n (35), obtained from hydrothermal reaction of HL 18 of Pb(NO 3 ) 2 , acted not only as a luminescent sensor for picric acid but also as a temperature sensor (Wang, 2019). More recently, Gai reported a novel Pb 2+ -containing polymer, [Pb(L 20 )]•0.5H 2 O•0.5CH 3 OH (36), containing a zwitterionic ligand 4-carboxy-1-(3,4dicarboxy-benzyl)-pyridinium chloride (H 3 L 20 Cl) (Supplementary Figure S2).…”

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.

In this study, the electrodeposition technique has been used to deposit low concentrations of highly toxic lead (Pb) cations into a solution of nitrate at a constant potential of -1V on fluorinedoped tin oxide electrodes (FTO). Monitoring of the reaction was conducted with the assistance of a computerized potentiostat/galvanostat setup, in cyclic voltammetry and in situ chronoamperometry modes. X-ray diffraction, scanning electron microscopy, energy dispersive X-Ray, and ultraviolet-visible spectroscopy techniques were used to examine the crystal structure, morphology, and optical properties of the lead deposits, respectively. Pb regular micro-hexagons have been identified; their size and density were significantly influenced by the cationic precursor's concentration. The correlation between the morphological and crystallographical structures of the electrodeposits was discussed. Based on chronoamperometric measurements, a mechanism for the growth of Pb deposits on FTO substrate has been proposed.Based on the reported results, electrodeposition processes of low heavy metals concentrations in contaminated water could be optimized using the eco-friendly electrodeposition technique.
