“…As shown in Figure a, the luminescent intensities and the peak positions of compound 1 are nearly consistent in the pH range of 3.0‐12.0, demonstrating that the luminescent emissions of compound 1 are stable in acidic and basic solutions. The alteration in fluorescence intensity of compound 1 in the different pH value may be attributed to the distinct energy transfer efficiency of ligands to metal centers . Encouraged by the good pH stability of luminescence, the PXRD patterns of the samples of compound 1 were carried out, and also display that the framework of compound 1 retains integrity in the pH range of 3.0‐12.0 (Figure b).…”

A new coordination polymer based on the 4-(2,2′;6′,2″-tripyridyl)-4′-1,2-phenyl dicarboxylic acid (H 2 tbda), namely, [Zn (tbda)] n (1), features a onedimensional binuclear chain structure and exhibits the excellent luminescence in pH range of 3-12 in aqueous solution. Particularly, compound 1 shows the remarkable selectivity, anti-interference, and recyclability for sensing Cr (III) ion through the fluorescence enhancement. Meanwhile, compound 1 can also serve as a sensor for detecting the trace amounts of Cr (VI) ion and 2,4,6trinitrophenol (TNP) with high selectivity and recyclability through the fluorescence quenching effect. Furthermore, the detection mechanisms of compound 1 as a fluorescence sensor for different analytes have been explored in detail.

“…These two types of materials have been shown to be successful as temperature sensors due to their multiple luminescence centers and highly tunable luminescence properties. In these materials, the lanthanide nodes, organic linkers, and guest molecules within the pores can all potentially generate luminescence . The presence of multiple luminescence centers allows the successful employment of these classes of materials for ratiometric luminescence thermometers.…”

Covalent Organic Frameworks (COFs), an emerging class of crystalline porous materials,are proposed as anew type of support for grafting lanthanide ions (Ln 3+ )a nd employing these hybrid materials as ratiometric luminescent thermometers.ATpBpy-COF-prepared from 1,3,5-triformylphloroglucinol (Tp) and 2,2'-bipyridine-5,5'-diamine (Bpy) grafted with Eu/Tb and Dy acetylacetone (acac) complexes can be successfully used as al uminescent thermometer in the 10-360 K( Eu) and 280-440 K( Tb) ranges with good sensing properties (thermal sensitivity up to 1.403 %K À1 ,t emperature uncertainty dT < 1Kabove110 K). Forthe Eu/Tb systems,we observe an unusual and rarely reported behavior,t hat is,n o thermal quenching of the Tb 3+ emission, aresult of the absence of ion-to-ligand/host energy back-transfer.T he LnCOF materials proposed here could be anew class of materials employed for temperature-sensing applications following up on the wellknownluminescent metal-organic framework thermometers.

“…These include Na, K, Mg, Ca, Fe, Zn, Mn, Cu, Co and Mo [1]. At the same time, some metals, such as rare earth elements (REEs), while revealing attractive catalytic properties in in vitro manipulations, leading to their wide use in industrial and medical applications [2][3][4], have been assumed biologically inert [5]. This assumption has been dramatically reversed recently with the demonstration of the activity of REEs lanthanides (Ln 3+ ) as cofactors of methanol dehydrogenases (MDH), enzymes essential in metabolism of single-carbon compounds such as methane and methanol [6][7][8][9][10][11][12][13][14].…”

Rare earth element alcohol dehydrogenases widely occur among globally distributed, numerically abundant and environmentally important microbes

et al. 2019

Lanthanides (Ln 3+), known as rare earth elements, have recently emerged as enzyme cofactors, contrary to prior assumption of their biological inertia. Several bacterial alcohol dehydrogenases have been characterized so far that depend on Ln 3+ for activity and expression, belonging to the methanol dehydrogenase clade XoxF and the ethanol dehydrogenase clade ExaF/ PedH. Here we compile an inventory of genes potentially encoding Ln 3+-dependent enzymes, closely related to the previously characterized XoxF and ExaF/PedH enzymes. We demonstrate their wide distribution among some of the most numerically abundant and environmentally important taxa, such as the phylogenetically disparate rhizobial species and metabolically versatile bacteria inhabiting world's oceans, suggesting that reliance on Ln 3+-mediated biochemistry is much more widespread in the microbial world than previously assumed. Through protein expression and analysis, we here more than double the extant collection of the biochemically characterized Ln 3+-dependent enzymes, demonstrating a range of catalytic properties and substrate and cofactor specificities. Many of these enzymes reveal propensity for oxidation of methanol. This observation, in combination with genome-based reconstruction of methylotrophy pathways for select species suggests a much wider occurrence of this metabolic capability among bacterial species, and thus further suggests the importance of methylated compounds as parts of the global carbon cycling.
