Molecular recognition of N-protected dipeptides by pseudopeptidic macrocycles: a comparative study of the supramolecular complexes by ESI-MS and NMR
(Royal Society of Chemistry, 2010)
The molecular recognition properties of pseudopeptidic macrocycles have been studied by ESI-MS and NMR spectroscopy, as highly complementary experimental techniques in solution and in the gas phase. We used ESI-MS competition ...
Effect of Hyaluronic Acid on the Self-Assembly of a Dipeptide-Based Supramolecular Gel
(Wiley, 2023-10-02)
The combination of polymers and low molecular weight (LMW) compounds is a powerful approach to prepare new supramolecular materials. Here we prepare two-component hydrogels made by a well-known and biologically active ...
Iron and chromium doped perovskite (CaMO3 M = Ti, Zr) ceramic pigments, effect of mineralizer
(Elsevier, 2012-08)
Solid solutions Ca(DxM1−x)O3 (M = Ti, Zr and D = Fe,Cr), have been studied as ceramic pigment in conventional ceramic glazes using 0.5 mol/mol of NH4Cl as flux agent by solid state reaction and by ammonia coprecipitation ...
Shvo’s catalyst and [IrCp*Cl2(amidine)] effectively catalyze the formation of tertiary amines from the reaction of primary alcohols and ammonium salts
(Wiley, 2011-08-04)
The reaction of (pentamethylcyclopentadienyl)iridium dichloride dimer, [IrCp*Cl2]2, with bis(2,4,6-trimethylphenyl)formamidine allows the preparation of two new [IrCp*Cl2(amidine)] and [IrCp*Cl(amidinate)] complexes, which ...
Synthesis of diphosphate Mn2−xMgxP2O7 solid solutions with thortveitite structure: New pink ceramic dyes for the colouration of ceramic glazes
(Elsevier, 2012)
Solid solutions of Mn and Mg mixed diphosphatesMn2-xMgxP2O7 (0.2 < x < 1.5) have been prepared by calcination (1000 °C/4 h) of coprecipitate precursors and characterized for the first time (through thermal analysis, XRD, ...
Rhodium and Iridium Complexes with Chelating C–C′-Imidazolylidene–Pyridylidene Ligands: Systematic Approach to Normal, Abnormal, and Remote Coordination Modes
(American Chemical Society, 2012)
A series of linked imidazolium−pyridinium salts
([Him-pyH](X)2
) have been used as imidazolylidene−
pyridylidene ligand precursors for the preparation of rhodium-
(III) and iridium(III) complexes. The relative configuration ...

En este artículo se estudia la microestructura y las propiedades ópticas y mecánicas de baldosas con efecto metalizado desarrollado tanto por deposición PVD de titanio en pasta roja y pasta blanca, y en baldosa de gres ...
Molecular Hydrogels from Bolaform Amino Acid Derivatives: A Structure–Properties Study Based on the Thermodynamics of Gel Solubilization
(Wiley, 2012-03)
Insight is provided into the aggregation thermodynamics associated to hydrogel formation by molecular gelators derived from L-valine and L-isoleucine. Solubility data from NMR measurements are used to extract thermodynamic ...
Low-Molecular-Weight Gelators: Elucidating the Principles of Gelation Based on Gelator Solubility and a Cooperative Self-Assembly Model
(American Chemical Society, 2008)
This paper highlights the key role played by solubility in influencing gelation and demonstrates that many facets of the gelation process depend on this vital parameter. In particular, we relate thermal stability (Tgel) ...
Supramolecular control for the modular synthesis of pseudopeptidic macrocycles through an anion-templated reaction
(American Chemical Society, 2008)
The anion-templated synthesis of different pseudopeptidic macrocycles has been studied in detail by using a multidisciplinary approach. The reaction between an open-chain pseudopeptidic diamine and the appropriate dialdehyde ...
