| Popis: | Guest selectivity in complexation of β-chitin with small molecules was studied. Since amines are strong agents for β-chitin complexation, selectivity for various amines was studied first. Of three isomers of phenylenediamine, the para isomer formed a complex, while ortho and meta isomers did not. The selectivity for linear aliphatic amines was examined for equimolar mixtures of various combinations, i.e., primary−secondary−tertiary amines of C6 main chain; C5 diamine and C6 monoamine; and C6 monoamine and C8 monoamine. The results showed a clear selectivity for primary amine over secondary and tertiary, diamine over monoamine, and longer alkyl chain over a shorter one. On the basis of such selectivity, complexation by guest incorporation from solution was established. This procedure allowed β-chitin complexation with high melting point compounds, to which pure liquid treatment was not applicable. By the solution treatment, complexes with acrylamide, p-aminobenzoic acid, and d-glucose were successfully pre... |
