Abstract AITranslate

Owed to their reversible diol-binding ability, phenylboronic acid (BA) derivatives have gained considerable interest for the development of saccharide sensors and drug delivery systems. In particular, BA-containing polymers have been used for the realization of sugar-responsive layer-by-layer (LbL) films. Herein, a LbL system based on cationic BA-homopolymers (PBA) is presented, and its subsequent sugar-induced disassembly is described. The BA-linear polymers (PBA) were intercalated with poly(vinylsulfonic acid, sodium salt) to form (PBA/PVS)n film assemblies. Different orientations of the boronic acid substituent (ortho-, meta-, and para-) in the PBA polymer were investigated for their influence on the LbL assembly. The rate of disassembly in the presence of glucose or fructose was analyzed by UV–vis spectroscopy. Additionally, the PVS component was replaced with an anionic fluorophore, pyranine (PYR), which allowed the assembly and disassembly to be monitored by fluorescence.
