Schiff Base Mediated Sol-Gel Polymerization
Published online by Cambridge University Press: 10 February 2011
Abstract
Formation of a Schiff base imine by reacting a primary amine with either an aldehyde or ketone was initiated by an aluminum compound acting as a Lewis acid catalyst. The water byproduct of the reaction then was used as an in situ reagent for subsequent hydrolysis and sol-gel condensation of the aluminum species. These reactions yielded a gel network containing the entrained Schiff base. Two examples of this synthetic approach are described with two different aluminum catalyst/reagents: a diethylaluminum diethylphosphate ester [(CH3CH2)2Al-O-P(O)(OCH2CH3)2] and triethyl aluminum [Al(CH3CH2)3]. Anhydrous ammonia and acetone were used as the Schiff base precursors.
