Combining equimolar of p-sulfonated calix[4]arene anion and triphenylbenzylphosphonium cation along with three molar of gadolinium(III) ions affords the typical bilayer arrangement while incorporating the same phosphonium cation in excess amount induces a porous-like array in the extended structure however without the uptake of the lanthanide in the final product. Addition of butyl-methylpyrrolidinium cation as a guest molecule demonstrates consistency to recent findings where the charged molecule is selectively drawn into the cavity with the long alkyl chain directs away from the cavity.
