“…In methanol, reaction leads to the exchange of the O-coordinated DMSO molecule with formation of [Ru(2-pytz)(DMSO) 3 Cl 2 ] ⋅ MeOH as well defined light-yellow crystals suitable for single crystal XRD analysis. This result is consistent with the previously published data on reactivity of cis-[Ru(DMSO) 4 Cl 2 ] and explained by increased lability of O-coordinated DMSO molecule in the trans-position to S-bound DMSO [24].…”

“…4, a Since preparation of Ru(II) complexes with 2-pytz via its direct interaction with RuCl 3 was found unsuccessful, we further attempted an alternative synthetic procedure that implied interaction of the nitrogenous ligand with a specially prepared Ru(II) precursor, i. e. cis-[Ru(DMSO) 4 Cl 2 ]. cis-[Ru(DMSO) 4 Cl 2 ] is known as a well-behaved Ru(II) precursor [23], and its behaviour in reactions with a variety of nitrogen-based ligands, including heterocyclic derivatives, is well documented [24]. However, no information is present in the literature on the reactivity of cis-[Ru(DMSO) 4 Cl 2 ] towards tetrazole derivatives.…”

“…Late transition metal complexes based on functionally substituted tetrazoles provide a promising avenue for the design of novel catalysts, luminescent materials and therapeutic agents [1][2][3][4][5][6]. Pyridyltetrazoles are of interest as potential ligands because their coordination to the metal can be effected by nitrogen atoms belonging both to the tetrazole ring and to the pyridine one.…”

Complexes [MII(2-pytz)Cl2] (M(II) = Pt, Pd; 2-pytz = 2-(tetrazol-1-yl)pyridine) were synthesised via direct interaction of the corresponding metal chlorides (K2PtCl4 or PdCl2) with 2-pytz under ambient conditions. RuCl3 does not react with 2-pytz under reflux in the protic media, while under reflux in N, N-dimethylformamide in the presence of LiCl, decomposition of the tetrazole cycle occurred leading to the formation of Ru(III)-coordinated N, N-dimethyl-N ′-(pyridin-2-yl)formimidamide derivative Li[RuIII(Py — N =C — NMe2)2Cl2]. The complex [Ru(2-pytz)(DMSO)3Cl2] ⋅ MeOH, where DMSO is dimethyl sulfoxide, was synthesised by reacting a specially prepared precursor cis-[Ru(DMSO)4Cl2] with 2-pytz in methanol under reflux conditions. The complex [Ru(2-pytz)(DMSO)2Cl2] was synthesised by reacting cis-[Ru(DMSO)4Cl2] with 2-pytz in ethanol under reflux conditions. The resulting complexes were characterised by elemental analyses, electrospray ionisation mass-spectrometry with detection of positive and negative ions, infrared spectroscopy, 1H and 13C nuclear magnetic resonance (NMR) spectroscopy, and simultaneous thermal analysis. The structures of complexes [Pd(2-pytz)Cl2] and [Ru(2-pytz)(DMSO)3Cl2] ⋅ MeOH were investigated by single-crystal X-ray analysis. In the former, 2-pytz shows a N,N-chelating coordination via the pyridine ring N and the tetrazole ring N2 atoms. In the latter, 2-pytz coordinates as a monodentate ligand via the tetrazole ring N4 atom. According to 1H NMR spectroscopy data, in complex [Ru(2-pytz)(DMSO)2Cl2], 2-pytz coordinates as a N, N-chelating ligand via the pyridine ring N and the tetrazole ring N2 atoms.

This study reports the use of waterborne acrylic resin as a polymer matrix for thin-film luminescent solar concentrators (LSC). A water dispersable lanthanide complex based on commercially available Eu 3+ chelate (Lumilux SDP Red, Lu Red) is utilized as the red-emitting pigment. The derived thin polymer films of about 100 μm show absorptions of the organic ligand comprised between 300 and 400 nm, flanked by scattering phenomena caused by the presence of the micro-sized pigment particles, whose dispersion is not adversely affected by concentration. The film's emission displays the typical fluorescence of Eu 3+ chelates around 600 nm with quantum yields between 20 and 36%. External quantum efficiencies (𝜼 ext ) are found to increase up to 4-4.5% with Lu Red content less than 10-15%, while dropping to about 3% at the highest content, possibly due to the adverse influence of the scattering phenomena within the waveguide. Maximum device efficiencies (𝜼 dev ) of 0.70% confirm the potentiality offered by the new LSC systems, thus definitely supporting the waterborne polymer matrices for the development of high-performance and water-based solar collectors.

The Schiff base N,N-bis(salicylidene)-o-phenylenediamine (salophen) was prepared by the condensation of salicylaldehyde with o-phenylenediamine in ethanol solution. Two new Zn(II) and Ni(II) salophen complexes, were synthesized, fully characterized by infrared (IR), 1H NMR spectroscopic measurements, UV–Vis spectra, photoluminescence (PL), and X-ray diffraction (XRD). The prepared complexes were used as phosphors to fabricate complexes/PMMA slab-based luminescent solar concentrators (LSC). The thermal stability of pure and doped PMMA polymer was examined by differential scanning calorimetry. Various parameters such as the optical energy gap, refractive index, AC and DC conductivity, dielectric constant, dielectric loss, Urbach energy, fluorescence quantum yield, and Stokes shift have been calculated and discussed. Optical absorption is carried out in wavelength region 200–900 nm at room temperature before and after the samples have been exposed to sunlight for up to 8 h. Photodegradation studies showed that the Zn(II) complex/PMMA LSC has the lowest rate of degradation compared with Ni(II) complex/PMMA LSC with the same concentration (0.06% weight). I–V characteristics of the photovoltaic devices with and without collectors were examined. The PV cell coupled with LSC shows an increase in maximum efficiency by about 50% compared to the normal one. This indicates that the proposed technique is very useful for improving the efficiency of solar cells.
