Abstract
In this Letter, we report optimized structures and lithium affinities of a series of anionic zeolitic fragments [H3Al(OCH3)x(OSiH3) 1-x- 2T, H2Al(OCH3)x(OSiH3) 2-x- 3T, Al(OCH3)x(OSiH3)4-x- 5T] that mimic the charge sites in polyelectrolytes. Ab initio molecular orbital methods at different levels of theory are used. The lithium affinities are much larger than the corresponding sodium affinities, indicating stronger interactions between lithium cations and these zeolitic fragments. The substitution of silicon by carbon increases the lithium affinity and the effect is generally larger than in the sodium systems.
