-
Sulfur-containing silanes were grafted onto magadiite (MGD) interlayer surfaces.
-
Silane grafting (Si69, MPTES) displaced CTA+ cations from the interlayer surfaces.
-
Reaction of squalene with silanized MGD probed accessibility of interlayer sulfur.
-
High Si69 graft density decreases MGD layer spacing and precludes entry of squalene.
-
Low Si69 graft density maintains layer spacing, permits interlayer squalene grafting.
