Interplay between hydrophilic and hydrophobic interactions in the self-assembly of a gemini amphiphilic pseudopeptide: from nano-spheres to hydrogels
(The Royal Society of Chemistry, 2012-02)
The formation of soluble nano-spheres or stable hydrogels through the self-assembling of a simple gemini amphiphilic pseudopeptide can be controlled by the tuning of the hydrophilic/hydrophobic interactions in aqueous medium.
Enantiomerically pure cyclopentadienyl- and indenyl-functionalized N-heterocyclic carbene complexes of iridium and rhodium
(American Chemical Society, 2011-08)
Novel enantiomerically pure cyclopentadienyl- and indenyl-functionalized N-heterocyclic carbene ligands have been prepared by reaction of a chiral imidazole tosylate derivative with the corresponding cyclopentadienyl and ...
Use fluorescence spectroscopy to study polymeric materials with porous structure based on imprinting by self-assembled fibrilar networks
(American Chemical Society, 2008)
Different polymeric materials have been prepared from the organogels formed by a polymerizable methacrylic mixture (methyl methacrylate/ethylene glycol dimethacrylate, 1:1, w/w) and the macrocyclic pseudopeptide 1. The use ...
pH-Tunable Hydrogelators for Water Purification: Structural Optimisation and Evaluation
(Wiley, 2012-02)
A focused library of potential hydrogelators each containing two substituted aromatic residues separated by a urea or thiourea linkage have been synthesised and characterized. Six of these novel compounds are highly efficient ...
Shedding Light on the Operation of Polymer Light-Emitting Electrochemical Cells Using Impedance Spectroscopy
(Wiley-VCH, 2012-01)
A combination of impedance spectroscopy, device characterization, and modeling is used to pinpoint key processes in the operation of polymer light-emitting electrochemical cells (LECs). At low applied voltage, electric ...
Metal Node Control of Brønsted Acidity in Heterobimetallic Titanium–Organic Frameworks
(American Chemical Society, 2023-01-23)
Compared to indirect framework modification, synthetic control of cluster composition can be used to gain direct access to catalytic activities exclusive of specific metal combinations. We demonstrate this concept by testing ...
Azonia spiro polyaza macrocycles containing biphenyl subunits as anion and cation receptors
(Elsevier, 2011-06-24)
The reaction of N-Boc triprotected cyclam with bis(chloromethyl)biphenyl followed by the corresponding deprotection of the nitrogen atoms allows the preparation of receptor 3 containing an azonia spiro subunit. This receptor ...

(MDPI, 2024-03-01)
Franklinite-zincochromite-gahnite solid solutions were prepared using ceramic or coprecipitation methods, and their pigmenting capacity as cool ceramic pigments in different glazes (double and single firing frits and ...
Photoluminescence Enhancement of CdSe Quantum Dots: A Case of Organogel–Nanoparticle Symbiosis
(American Chemical Society, 2012)
Highly fluorescent organogels (QD–organogel), prepared by combining a pseudopeptidic macrocycle and different types of CdSe quantum dots (QDs), have been characterized using a battery of optical and microscopic techniques. ...
Synthesis and biological properties of the cytotoxic 14-membered macrolides aspergillide A and B
(Wiley, 2010-11-09)
Total, stereoselective syntheses of the naturally occurring, cytotoxic macrolides aspergillide A and B are described. Olefin metatheses and asymmetric allylations were key steps in the synthetic sequences. Cytotoxicity ...
