Neutral organic redox pairs based on sterically hindered hydroquinone/benzoquinone derivatives for dye-sensitized solar cells
(2018-06)
Substituted derivatives of hydroquinone/benzoquinone were studied as organic redox mediators in the electrolyte for dye-sensitized solar cells (DSSCs). Thus, di-tert-butylhydroquinone (DTHQ), thymohydroquinone (ThymHQ) and ...
Synthesis and Crystal Structure of a Copper(II) Benzoate Complex Bearing a Bis-2,2′-Tetrahydrofuryl Peroxide Moiety
(2018-12)
Complex [Cu2(ben)4·2THF−(η1–O2)]∞ (2) (ben=C6H5CO2− benzoate; THF=tetrahydrofuran) was isolated when a solution of Cu2(ben)4·2THF (1) in THF upon natural sunlight irradiation yields crystals suitable for single-crystal ...
1,3-Bis{[(2,6-dimethylphenyl)sulfanyl]methyl}benzene
(2019)
The structure of the title compound, C24H26S2, an example of a pincer ligand with an SCS-chelation motif, illustrates the steric effects of the methyl groups in the thiophenyl rings at the 2- and 6-positions, forcing a ...
Direct functionalization of Mn12-(methacrylate) clusters on Si(100): surface characterization and electrochemical properties
(2016-09)
The reaction of H–terminated Si(100) with methacrylate–substituted manganese carboxylate clusters [Mn12O12{CH2C(CH3)COO}16(H2O)4], [Mn12–(methacrylate)] via hydrosilylation afforded Mn12–(methacrylate)−Si(100). The chemically ...
Dye‐sensitized Devices: Photovoltaic and Photoelectrolytic Applications
(2018-11)
Dye‐sensitized approach along with stability and surface robustness in titanium dioxide (TiO2) against photocorrosion and degradation has been widely studied and applied in several important applications. This chapter ...
Synthesis, structure and spectroscopic characterization of Ni(II), Co(II), Cu(II) and Zn(II) complexes with saccharinate and pyrazole
(2007-09)
Four mononuclear mixed-ligand complexes of Co(II), Ni(II), Cu(II) and Zn(II), with saccharin (sac) and pyrazole (Hpz) were synthesized and characterized on the basis of elemental analysis, FT-IR spectroscopy, magnetic ...

(2015-02)
The molecular structures of several related cis-[j2-SS-(L)MHal2] compounds 1, 1DMSO, 2, 2H2O,
3DMSO, 4 and 5 where L = HOCH2Ph-S-CH2-CH2-S-PhCH2OH, M = Pd or Pt, and Hal = Cl or Br or I, were analyzed by single crystal ...
N-[3-(Prop-1-yn-1-yl)phenyl]benzenesulfonamide
(2019)
In the title sulfanilamide derivative, C15H13NO2S, which shows significant
activity against Staphylococcus aureus and Escherichia coli, the dihedral angle
between the planes of the aromatic rings is 62.15 (19)° and the ...
