Abstract
Multilayer thin films of cationic phosphorous dendrimers and anionic hyperbranched polyglycerols were fabricated by electrostatic layer-by-layer (LbL) self-assembly (SA). The film formation was monitored by surface plasmon resonance (SPR) spectroscopy and UV-visible spectroscopy, and it was found that the stepwise, alternating deposition results in a linear growth up to four bilayers. Hybrid organic-TiO 2 nanostructures were generated by exposing the supramolecular multilayers to TiCl 4 precursors. The amounts of TiO 2 incorporated inside the scaffolds could be tuned by controlling the porosity of the multilayers with the addition of a small amount of salts. The resulting hybrid films exhibit characteristic photoluminescence (PL) properties. Copyright © 2006 American Scientific Publishers All rights reserved.
