摘要：
Catalysts in a bottle are readily prepared by coelectrospinning of PAMAM dendrimers and polyethylene 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. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
