Reusable Catalysts Based on Dendrimers Trapped in Poly(p‐xylylene) Nanotubes

Catalysts in a bottle are readily prepared by coelectrospinning of PAMAM dendrimers and poly(ethylene oxide) (PEO). The nanofibers thus obtained can be coated with poly(p‐xylylene) by chemical vapor deposition. Removal of the core PEO fibers by extraction with water results in PAMAM dendrimers entrapped in the tubes (see picture). The entrapped dendrimers show a high catalytic activity as reusable organocatalysts.
