Abstract in another language
Applying a nema tic liquid crystalline phase of a synthetic Na-hectorite with layer separations >100 nm, the reaction time for pillaring with Al-13 Keggin oligocation could be reduced to seconds ensuring that cation exchange is controlled by thermodynamics. With this material at hand we are able to resolve the long-standing dispute regarding the charge of intercalated Keggin oligocations. Micropore sizes as determined by physisorption isotherms, adsorption isotherms obtained via elemental analysis, and results of Al-27 solid-state NMR and pyridine probe IR spectroscopy favor a charge of +7 for the Al-13 pillars intercalated into hectorite unaltered.
