| Popis: | Multilayer nanoscale Langmuir-Blodgett films based on diphilic β-cyclodextrins with various numbers of alkyl chains were grown on single-crystal silicon substrates both unmodified and modified by cationic and anionic polyelectrolyte layers using the polyion complex technique. Ratios of β-cyclodextrin monolayer transfer on substrates were calculated and analyzed. It was shown that this ratio depends on the sign of the polyelectrolyte adhesive layer charge, as well as on the number of alkyl chains in the β-cyclodextrin molecule and the number of deposited monolayers. The observed phenomena characterizing indicator properties of β-cyclodextrin monolayers were interpreted. |
