How do amino acids behave in intercalation compounds? — •Robby Büchner1, Annette Pietzsch1, and István Pálinkó2 — 1Helmholtz-Zentrum Berlin für Materialien und Energie, Germany — 2University of Szeged, Hungary
The first soft X-ray spectra of a Layered Double Hydroxide (LDH) and intercalated amino acids are presented. LDHs are clay minerals with the ability to store arbitrary anionic guest species between their positively charged layers. This property enables numerous applications ranging from environmental remediation, to controlled drug delivery and even gene transfer. In order to systematically develop and improve these applications, a profound understanding of the host-guest interactions is essential. Therefore, near-edge X-ray absorption fine structure (NEXAFS) and resonant inelastic X-ray scattering (RIXS) measurements were carried out. They confirmed the widely assumed Coulomb attraction between the LDH host and the guest ions. Additionally, an at least partially covalent bond between the host layers and the amino acids can be stated.
