Ein schachbrettartiges Muster: Saccharinsäure, eine billige chirale Ausgangsverbindung für mögliche „grüne“ heterogene Katalysatoren und Molekularsiebe, bildet ein stabiles kristallines Zinkderivat, dessen Kristallstruktur zwei Typen von Kanälen, einen hydrophilen und einen hydrophoben, mit stark unterschiedlichen Merkmalen enthält. Die Kanäle sind durch anscheinend undurchdringliche Wände getrennt, wodurch ein schachbrettartiges Muster entsteht (siehe Bild).
A chessboard pattern: Saccharic acid, which could become a cheap chiral feedstock for possible “green” heterogeneous catalysts and sieves of the future, gives a robust crystalline zinc derivative, which is unusual in having within the same crystal structure two types of channels with very different characteristics: one hydrophilic, the other hydrophobic. These channels are isolated from each other by seemingly impenetrable walls, which produces, in projection, the pattern shown.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
