Ik sta hier vandaag met gemengde gevoelens. Het communicatievak bevindt zich namelijk in een deplorabele situatie (dat is overigens zeker niet alleen bij de overheid en publieke organisaties het geval: bij commerciële organisaties is het niet beter gesteld). De andere kant van de medaille is dat …

Cyclohexane-based low molecular weight hydrogelators

Friggeri, Arianna; van der Pol, Cornelia; van Bommel, Kjeld J C; Heeres, André; Stuart, Marc C A; Feringa, Ben L; van Esch, Jan

Seven new 1,3,5-cyclohexyltricarboxamide-phenylalanine derivatives were synthesized in order to investigate the effect of the amino acid chirality on the gelating properties of these small molecules in water. Gelation tests have shown that enantiomerically pure homochiral 1,3,5-cyclohexyltricarboxamide-L-phenylalanine …

Responsive cyclohexane-based low-molecular-weight hydrogelators with modular architecture

van Bommel, Kjeld J C; van der Pol, Cornelia; Muizebelt, Inouk; Friggeri, Arianna; Heeres, André; Meetsma, Auke; Feringa, Ben L; van Esch, Jan

pH-sensitive gels: By using a cyclohexane-based scaffold to which various amino acid based substituents can be connected, low-molecular-weight compounds were obtained that can gelate water at very low concentrations. Their modular design (see picture: AA = amino acid(s), X = hydrophilic substituent, …

Orthogonal self-assembly of low molecular weight hydrogelators and surfactants

Heeres, Andre; van, der Pol Cornelia; Stuart, Marc; Friggeri, Arianna; Feringa, Ben L.; van, Esch Jan

The concurrent self-assembly of new 1,3,5-trisamide-cyclohexane-based low molecular weight hydrogelators and various surfactants in water leads to the formation of self-assembled fibrillar networks with encapsulated micelles. This prototype system presents an example of orthogonal self-assembly, that …
