“…This might be due to fluorescence quenching within the sample matrix. Benzotriazoles have been shown to form ligands with transitional metals (Shen et al, 2007;Wang et al, 2010), and thus the formation of ligands within the sample matrix may have caused quenching and ultimately decreased fluorescence intensity.…”

Snowpacks in urban environments can retain a high load of anthropogenic contaminants that, upon melting, can deliver concentrated contaminant pulses into the aquatic environment. In climates with an extended period of snowfall accumulation, such as in Anchorage, Alaska, contaminant amplification within meltwater may affect aquatic ecosystem health. A spatiotemporal study of benzotriazoles on snow, meltwater and soils was performed in association with three urban snow disposal facilities. Benzotriazole elution from engineered snow disposal sites behaved similarly to inorganic salt and dissolved organic carbon (DOC) during the initial melt period, with maximum concentrations between 2.23-7.39 μg/L; similar enrichment was observed in creeks. Assays of disposal site soils revealed the presence of tolytriazole. Furthermore, using fluorescence spectroscopy and PARAFAC analysis, a modeled component representative of benzotriazoles was identified, a possible indicator of anthropogenic input rather than a unique indicator for benzotriazole compounds.

“…However, the use of the isonicotinic acid analogue 2-phenylquinoline-4-carboxylic acid (HL) to construct metalorganic frameworks has been less thoroughly investigated to date (Qin et al, 2002;Shen et al, 2007;Wang et al, 2010;Li et al, 2011;Zhang et al, 2009). The 2-phenylquinoline-4-carboxylate ligand, L, was selected based on the following considerations.…”

A novel supramolecular framework, catena-poly[[[aqua(2-phenylquinoline-4-carboxylato-κO)silver(I)]-μ-4,4'-bipyridine-κ(2)N:N'] dihydrate], {[Ag(C16H10NO2)(C10H8N2)(H2O)]·2H2O}n, has been synthesized and structurally characterized. The Ag(I) centres are four-coordinated and bridged by 4,4'-bipyridine (4,4'-bipy) ligands to form a one-dimensional Ag-bipy chain. The Ag-bipy chains are further linked together by intermolecular O-H···O and O-H···N hydrogen-bonding interactions between adjacent chains, resulting in a three-dimensional framework.

“…Therefore, the 4,4 -bpy ligands link Cd(II) ions to form the one dimensional structure in compound II and compound I is the binuclear cluster by the carboxylate bridge and phen chelate to Cd(II) ions, in which the different structures are understandable in comparison with some previous reports in terms of coordination chemistry.

“…2-Phenylquinoline-4-carboxylic acid (Hpqc), aside from its significance in biological systems, [7,8] also possesses fascinating coordination behaviors, such as asymmetric geometry and multiple coordination sites, which have been widely used to design and synthesize metal-organic coordination complexes because of the carboxylate group and/or pyridine nitrogen atom. [9][10][11][12][13][14][15] Zinc is a flexible transition metal in adopting various coordination geometries in its complexes. In this article, we report the synthesis and characterization of compound I and compound II.…”

phen = 1,10-phenanthroline, bpy = 4,4 -bipyridine). Complexes I and II have been characterized by x-ray single-crystal diffraction, infrared (IR), powder x-ray diffraction (PXRD), thermogravimetric analysis (TGA), and fluorescence spectra. Structural analysis reveals that I is binuclear in structure; two Zn(II) centers are bridged by two carboxylate groups and the terminal water molecule occupies a axial position of the octahedral geometry, which further extends the binuclear unit into a supramolecular framework via intermolecular hydrogen bonding and π ···π interactions. Complex II possesses a one-dimensional infinite zigzag chain architecture by bridging of the 4,4 -bipyridne.
