摘要：

Amphiphilic polysulfonates containing 1-adamantyl (Ad) or 1-naphthylmethyl (Np) groups were treated with didodecyldimethylammonium bromide (DDAB) (double-chain cationic surfactant) to yield Coulombic complexes which were soluble in common organic solvents. H-1-NMR spectra, 2D-NOESY, and NMR relaxation times for the complex of the Np-containing polymer in organic solution revealed that the motions of the Np residues were highly restricted, while those of the DDAB residues were much less restricted. These findings imply that the micelle structure of the parent amphiphilic polysulfonates in aqueous solution remained rather intact in the complexes even though they were dissolved in organic solvents. Covalently attached spin probes indicated that the complex was in a particularly compact form in benzene. Fluorescence emitted by pyrene incorporated in the complexes supported these findings.
