Author is Zhang, Sheng; Mo, Wenjiao; Zhang, Jiangwei; Zhang, Zengqi; Yin, Bing; Hu, Dengwei; Chen, Sanping.

A series of mononuclear DyIII compounds, [Dy(tmpd)3(4,4′-dmpy)] (1), [Dy(tffb)3(4,4′-dmpy)] (2), [Dy(tffb)3(5,5′-dmpy)] (3), and [Dy(tmpd)3(5,5′-dmpy)] () [tmpd = 4,4,4-trifluoro-1-(4-methoxyphenyl)-1,3-butanedione, tffb = 4,4,4-trifluoro-1-(4-fluorophenyl)-1,3-butanedione, 4,4′-dmpy = 4,4′-dimethyl-2,2′-bipyridyl, and 5,5′-dmpy = 5,5′-dimethyl-2,2′-bipyridyl], have been synthesized by modifying β-diketonate ligands and capping N-donor co-ligands. DyIII ions in 1-4 possess N2O6 octacoordinated environments. Compounds 1 and 2 exhibit distorted trigonal dodecahedron configurations, while 3 and 4 display distorted square antiprismatic configurations. Systematic investigations of the a.c. measurements indicate the different magnetic relaxation dynamics with energy barriers (Ueff) of 66 K (1, 45 cm-1), 189 K, (2, 131 cm-1), 115 K (3, 79 cm-1), and 205 K (4, 142 cm-1). To deeply understand their different magnetic behaviors, the magnetic anisotropies of 1-4 were studied by ab initio calculations From ab initio calculations, the energies of the first excited state (KD1) are consistent with the exptl. Ueff under zero d.c. field. Compound 4 presents the largest Ueff because of the smallest gX,Y and μqTM as well as the most strong axial crystal field parameters (CFPs) among compounds 1-4. The M vs. H data exhibit butterfly-shaped hysteresis loops at 2 K for 1-4. The different coordination geometries, the magnetic dynamics, the electrostatic repulsion, and CFPs result from the different substituent effects of ligands, including the electronic effect, the steric effect, and the positions of substituted groups. The different coordination geometries, the magnetic dynamics, the electrostatic repulsion, and the crystal field parameters result from the different substituent effects of ligands, including the electronic effect, the steric effect, and the positions of substituted groups.

Name: 5,5′-Dimethyl-2,2′-bipyridine. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles.

Author is Chen, Kai-Hong; Wang, Ning; Yang, Zhi-Wen; Xia, Shu-Mei; He, Liang-Nian.

Developing an efficient and easy-to-handle strategy in designing catalysts for CO2 reduction into CO by harnessing sunlight is a promising project. Here, a facile strategy was developed to design a Re catalyst modified with an ionic secondary coordination sphere for photoreduction of CO2 to CO by visible light. By adding ionic liquids or tuning a different ionic secondary coordination sphere, it was discovered that an outstanding optical property, other than CO2 absorption ability or the ability to dissociation of chloride anion, is the prerequisite for catalyst design. Accordingly, a novel Re catalyst, {Re[BpyMe(tris(2-hydroxyethyl)amine)](CO)3Cl}Br (Re-THEA), was designed, screened, and resulted in a relative high quantum yield (up to 34 %) for visible-light-induced CO2 reduction with a single-mol. system. DFT calculations, combined with exptl. outcomes, suggested the pendant ionic tris(2-hydroxyethyl)amino (THEA) group on Re-THEA can enhance visible-light absorption, stabilize reaction intermediates, and suppress the Re-Re dimer formation.

The size of N-N ligand and its substituents modulate the compound electronic features and influence their antiproliferative efficiency against Entamoeba histolytica, 56dmphen derivative, shows the biggest molar volume and presents a powerful amoebicidal activity (IC50 = 1.2μM), being seven times more effective than the first-line drug for human amoebiasis metronidazole. Also, increases the reactive oxygen species concentration within the trophozoites. This could be the trigger of the E. histolytica growth inhibition. The antiparasitic effect is described using NiII electron d., molar volume, estimated by DFT, as well as the exptl. redox potential and diffusion coefficients In general, amoebicidal efficiency is directly proportional to the increment of the molar volume and decreases when the redox potential becomes more pos.

Poly(L)n films offer a number of future perspectives ranging from organic photovoltaic to photoelectrochem. catalysis and sensing.

While numerous Eu3+ complexes are known now that can efficiently be exploited at 350-400 nm excitation range, corresponding green Tb3+ emitter complexes are hard to find. Tb3+ salts of fenamic acid and derivatives thereof are interesting candidates for applications using near-UV excitation: on addnl. co-coordination with e.g. 5,5′-dimethyl-2,2′-bipyridine, excitation maximum at 380 nm, at the same time maintaining high efficiencies, can be accomplished.
