Abstract
On the basis of hydrogen bonding directed layer-by-layer (LbL) assembly we have fabricated two multilayer systems, poly(acrylic acid) bearing spironaphthoxazine (PAA-SO)/poly(4-vinylpyridine) and carboxyl-terminated polyether dendrimer (dendrimer-COOH)/poly(4-vinylpyridme). UV-Vis spectroscopy indicates that either PAA-SO or dendrimer-COOH can be released from the corresponding multilayer assemblies upon immerssion in a basic aqueous solution. Furthermore, the rate of molecule release can be controlled either by changing the pH value or by adjusting the layer structure.
