Preferential orientations of structure directing agents in zeolites

Abstract

The local structure of as-synthesised silicalite-1 zeolites is modified using asymmetric R(Pr)3N+ structure directing agents. Using multi-nuclear NMR (1H, 13C, 14N, 19F, 29Si), we show for the first time the ability of these cations to adopt preferential orientations at the zeolite channels' crossing.
