The effect of guest molecular architecture and host crystallinity upon the mechanism of the intercalation reaction

---

Abstract.
The intercalation process of α-zirconium phosphate (α-ZrP) was investigated by using two α-ZrP samples
with different levels of crystallinity and two structurally different intercalating molecules, i.e., linear
hexylamine and non-planar cyclohexylamine. The results show that the intercalation energy barrier,
which is affected by both host α-ZrP and guest intercalating molecules, has a significant effect on the
intercalation process. When the intercalation energy barrier is relatively low, the interlayer distance of
α-ZrP expands continuously with increasing amount of intercalating molecules. When the energy barrier
reaches a certain level, the interlayer distance expansion becomes stepwise. The observed differences in
the intercalation process correspond well with the geometric arrangement of the intercalated molecules
inside the gallery of α-ZrP.
