Synthesis of divalent ligands of beta-thio- and beta-N-galactopyranosides and related lactosides and their evaluation as substrates and inhibitors of Trypanosoma cruzi trans-sialidase
(Beilstein-institut, 2014-12)
In this work we describe the synthesis of mono- and divalent β-N- and β-S-galactopyranosides and related lactosides built on sugar scaffolds and their evaluation as substrates and inhibitors of the Trypanosoma cruzi ...
Synthesis, characterization, spectroscopic and electrochemical studies of donor–acceptor ruthenium(II) polypyridine ligand derivatives with potential NLO applications
(Elsevier, 2015)
In this work we report the preparation of six new donor–metal–acceptor (D–M–A) type complexes of
ruthenium(II) with the highly absorbing ‘‘chromophoric’’ ligand 4,40-bis(2-(4-methoxyphenyl)styryl)-
2,20-bipyridine, ...
Luminescent europium(iii) and terbium(iii) complexes of beta-diketonate and substituted terpyridine ligands: synthesis, crystal structures and elucidation of energy transfer pathways
(2019)
In this work, we synthesized and structurally characterized a series of six coordinatively saturated Eu-III and Tb-III complexes: [Ln(R-TPY)(TTA)(3)] (1-6), having three beta-diketonate ligands i.e.TTA = 1,1,1-trifluoro- ...
Luminescence and non-radiative processes in lanthanide squarate hydrates
(1996-11-01)
The luminescence properties of solid hydrated lanthanide squarates (Ln2(C4O4)3(H2O) x; x = 8 or 13;Ln3+ = Gd, La, Eu, Tb, Pr) are reported for temperatures down to 4.2K. The luminescence of the squarate group is observed ...

Electrochemical studies of copper(II) complexes with Schiff-base ligands
(PERGAMON-ELSEVIER SCIENCE LTD, 2002-01-15)
The electrochemical reduction of copper(II) complexes with salen Schiff-base ligands derived from ethylenediamine or (R,R) or (S,S)-1,2-diphenylethylenediamine and 5-methoxy, 5-bromo and 5-nitrosalicylaldehyde have been ...
Photosubstitution of Monodentate Ligands from RuII–Dicarboxybipyridine Complexes
(Wiley VCH Verlag, 2017-08)
We report the photophysical and photochemical properties of RuII–polypyridine complexes [Ru(bpy)(dcbpy)py2]2+ (1)2+ and [Ru(dcbpy)2py2]2+ (2)2+ (bpy = 2,2′-bipyridine, dcbpy = 4,4′-dicarboxy-2,2′-bipyridine, py = pyridine). ...
