Probing the Molecular Level Structure in Aluminum Containing Bifunctional Mesoporous Organosilicas: A Solid-State NMR Study

摘要

Aluminum containing -CH2CH2-/-CH=CH-PMOs have been synthesized and folly characterized at both the macro- and molecular level using PXRD, N2 adsorption and solid-state NMR. ~1H-~(29)Si HETCOR experiments confirmed the homogenous distribution of organic functionalities within the framework. Whereas ~1H-~(27)A1 HETCOR NMR indicated the aluminum to be evenly distributed throughout the framework and located near both organic bridges.
