Molecular assembly recognition process. Carbon number selective intercalation of amines by a layered zirconium phosphonate
Abstract
The reaction of n-alkylamines CnH2n+1NH2(n= 1–10) with a partially phosphated zirconium carboxyethyl-phosphonate shows that only heptylamine (n= 7) is preferentially intercalated to form a bilayer, demonstrating a new class of host–guest process based on molecular assembly recognition.
