Kinetics or thermodynamics? Extolling their role to modulate the crystal phases and luminescence of KY3F10:Eu3+ powders
(Royal Society of Chemistry, 2023-09-28)
KY3F10, a fluoride compound with two polymorphs (alpha and delta), has been a subject of study due to its unique properties. Obtaining the metastable delta-phase has been challenging, but this study presents an enhanced ...
Organogel–quantum dots hybrid materials displaying fluorescence sensitivity and structural stability towards nitric oxide
(Royal Society of Chemistry, 2012-03)
Nanoparticle doped hybrid organogels were prepared using the pseudopeptidic macrocycle 1 and CdSe/
ZnS quantum dots (QDs). The new semi-solid materials show the same thermal stability and excellent
optical transparency ...
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 ...
Efficient Synthesis of Pseudopeptidic Molecular Cages
(Wiley, 2012-04)
Pseudopeptidic cages have been efficiently prepared by combining a dynamic covalent procedure with the suitable preorganization of the building blocks by a conformational bias or an anion templation.
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 ...
Pyracenebis(imidazolylidene): a new Janus-type biscarbene and its coordination to rhodium and iridium
(American Chemical Society, 2012)
A pyracene-linked bis-azolium compound has been obtained from the bisannulation of tetrakis(iminopyracene) (TIP) with chloromethyl methyl ether. The resulting bisazolium salt was readily coordinated to rhodium and iridium, ...
Solid-State Polymorphic Transition and Solvent-Free Self-Assembly in the Growth of Organic Crystalline Microfibers
(American Chemical Society, 2008)
The study of the crystalline xerogel formed by a newly synthesized l-valine and pyridine containing low-molecular-weight gelator reveals a polymorphic transition above 225 °C that is followed by the formation of microfibers. ...
Inorganic and Hybrid Nanofibrous Materials Templated with Organogelators
(American Chemical Society, 2008)
This article presents a general overview about the designed synthesis of one-dimensional (1-D) inorganic
and organic–inorganic hybrid fibrous nanostructures templated through the use of organogelator-based
supramolecular ...
Zinc(II) coordination polymers with pseudopeptidic ligands
(Royal Society of Chemistry, 2011-10-11)
Two new phenyl-bridged pseudopeptidic ligands have been prepared and structurally characterised. The nature of the ligands’ substituents play an important role in the nature of the solid state structure yielding either ...
