Embedding and Positioning of Two FeII4L4 Cages in Supramolecular Tripeptide Gels for Selective Chemical Segregation

An unreported d,l-tripeptide self-assembled into gels that embedded FeII4L4 metal–organic cages to form materials that were characterized by TEM, EDX, Raman spectroscopy, rheometry, UV/Vis and NMR spectroscopy, and circular dichroism. The cage type and concentration modulated gel viscoelasticity, an...

When two different cages were added to spatially separated gel layers, the gel–cage composite material enabled the spatial segregation of a mixture of guests that diffused into the gel. Each cage selectively encapsulated its preferred guest during diffusion.

El tipo de jaula y la concentración modularon la viscoelasticidad del gel y, por lo tanto, la tasa de difusión de los huéspedes moleculares a través de la matriz nanoestructurada, medida por 19 F y 1Espectroscopía de RMN H. Cuando se agregaron dos jaulas diferentes a capas de gel separadas espacialmente, el material compuesto de jaula de gel permitió la segregación espacial de una mezcla de invitados que se difundió en el gel. Cada jaula encapsuló selectivamente a su huésped preferido durante la difusión. Por lo tanto, presentamos una nueva estrategia para utilizar interacciones supramoleculares anidadas para permitir la separación de moléculas pequeñas.Wiley202220222019info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/30508reponame:RUIdeRA.
