摘要

On the basis of hydrogen bonding directed layer-by-layer (LbL) assembly we have fabricated two multilayersystems

poly(acrylic acid) bearng spironaphthoxazine (PAA-SO)/poly(4-vinylpyridine) and carboxyl-terminated polyetherdendrimer (dendrimer-COOH)/poly(4-vinylpyridine). 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.
