Hyperbranched polymers with a degree of branching of 100% were prepared and converted into different types of unimol. micelle-like structures. The polymers were obtained by acid catalyzed polycondensation of an isatin-based AB2 monomer, prepared without using toxic organometal reagents or extensive chromatog. purification The molar masses as determined by SEC relative to linear PS standards were strongly underestimated as compared to absolute data determined by MALLS. This could be accounted for by the densely branched structure and the formation of intramol. hydrogen bonds. The hyperbranched scaffolds were converted into unimol. micelle-like structures in two ways. In a first approach, long alkyl chains were introduced at the terminal units and carboxyl groups at the dendritic units. The resulting macromols. were soluble in apolar solvents and able to bind polar dyes. Alternatively, the terminal units could be converted into quaternary ammonium salts, leading to water-soluble macromols. binding apolar BODIPY dyes.
