Acyclic Pseudopeptidic Hosts as Molecular Receptors and Transporters for Anions
Wiley-VCH Verlag (2015)The synthesis and characterization of different pseudopeptidic hosts derived from open chain systems with C2 and C3 symmetry has been achieved. These receptors are based on structures containing phenylalanine amino acid ... -
Anion-Responsive Diguanidinium-Based Chiral Organogelators
Wiley (2012-10)The chiral bicyclic diguanidinium chloride 1 forms gels in aromatic apolar solvents. The gels were characterized at different levels of organization, from the macroscopic to the molecular level by using microscopy, ... -
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 ... -
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. -
In situ synthesis-gelation at room temperature vs. heating–cooling procedure. Fine tuning of molecular gels derived from succinic acid and L-valine
Elsevier (2013-12)Hypothesis The reaction between succinic anhydride and a diamine derived from L-valine should afford efficiently a molecular gelator. Based on this reaction, it should be feasible to prepare molecular gels at room ... -
Multimodal Light-Harvesting Soft Hybrid Materials: Assisted Energy Transfer upon Thermally Reversible Gelation
American Chemical Society (2017)Multimodal light-harvesting soft systems able to absorb UV-to-NIR radiations and convert into visible emissions have drawn much attention in the last years in order to explore new areas of application in energy, photonics, ... -
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 ... -
Self-Assembly Studies of a Chiral Bisurea-Based Superhydrogelator
Wiley (2012-11)A chiral bisurea-based superhydrogelator that is capable of forming supramolecular hydrogels at concentrations as low as 0.2 mM is reported. This soft material has been characterized by thermal studies, rheology, X-ray ... -
Substrate selective catalytic molecular hydrogels: the role of the hydrophobic effect
Royal Society of Chemistry (2013-09-17)A catalytic hydrogel is reported for the substrate selective direct aldol reaction of aliphatic ketones based on their hydrophobicity and on the emergence of catalytic activity only after self-assembly of the catalyst. -
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 ... -
Switchable Perfomance of an l-Proline-Derived Basic Catalyst Controlled by Supramolecular Gelation
American Chemical Society (2009)An l-proline-derived low molecular weight gelator forms gels in nitromethane and nitroethane and acts as a basic catalyst for the Henry nitroaldol reaction of these solvents with 4-nitrobenzaldehyde and 4-chlorobenzaldehyde. ... -
Template Effects in SN2 Displacements for the Preparation of Pseudopeptidic Macrocycles
Wiley (2012-02)Macrocyclisation reactions of C2-symmetric pseudopeptides containing central pyridine-derived spacers are affected by the presence of different anions. The selection of the proper anion gives excellent results for the ...
