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.
