    • The materials prepared with higher loadings of thiol were only tested for catalysis (next section), rather than scavenging studies, and gave materials that were active catalysts with no discernible difference in activity thus far.

    • note
    • Samples taken at low conversions (22%, 42%) show no increase in leaching, indicating that the catalyst is not leaching and readsorbing after the reaction.

    • note
    • Although the catalyst is stable in solid form, and few precautions need to be taken at the beginning of the reaction in terms of exclusion of air; the reaction is sensitive to oxygen once it has begun.
