Das Sortieren von C4‐Olefinen gelingt mithilfe einer Kombination aus molekularer Erkennung und Größensiebeffekt. In ihrer Zuschrift auf S. 16500 berichten H. B. Xing und Mitarbeiter über verzahnte poröse Hybridmaterialien mit anionischen Säulen, funktionellen Zentren (die Seerosen) und Hohlräumen (die Durchfahrt unter der Brücke), deren Größe in 0.2‐Å‐Schritten fein einstellbar ist. Die Materialien...
C4 olefin separations present one of the great challenges in hydrocarbon purifications owing to their similar structures, thus a single separation mechanism often met with limited success. Herein we report a series of anion‐pillared interpenetrated copper coordination for which the cavity and functional site disposition can be varied in 0.2 Å scale increments by altering the anion pillars and organic...
