Dye-Encapsulation Selectivity of Amphiphilic Dendritic Boxes
Amphiphilic hyperbranched polyamidoamine (PAMAM) and poly(sulfone-amine) (HPSA) were prepared and their dye-encapsulation properties were investigated. Both of them can carry water-soluble dyes from aqueous solution into chloroform. The selectivity of host to guests and the influence of interaction between different dyes on loading capacity were also investigated by performing comparable experiments. Encapsulation capacities are considered to have relationship with the water-solubility of the hyperbranched polymer core, the polarity difference between the hydrophilic core and the hydrophobic shell, the molecular structure of dyes, and the interactions between dyes.
