| Abstract | Novel amphiphilic comb-dendronized diblock copolymers composed of hydrophobic Percec-type dendronized polystyrene block and hydrophilic comb-like poly(ethylene oxide) grafted polymethacrylate P(PEOMA) block were designed and synthesized via two steps of atom transfer radical polymerization (ATRP). The comb-like P(PEOMA) prepared by ATRP of macromonomers (PEOMA) with two different molecular weights (Mn = 300 and 475) were used to initiate the Sequent ATRP of dendritic styrene macromonomer (DS). The molecular weights and compositions of the obtained block copolymers were determined by (1)H NMR analysis. The copolymers with relatively narrow polydispersities (1.27-1.38) were thus obtained. The bulk properties of comb-dendronized block copolymers were studied by using differential scanning calorimetry, polarized optical microscopy and wide-angle X-ray diffraction (WAXD). Similar to dendronized homopolymers, the block copolymers exhibited hexagonal columnar liquid-crystalline phase structure. By using such amphiphilic comb-dendronized block copolymers as building blocks, the rich self-assembly morphologies, such as twisted string, vesicle, and large compound micelle (LCM), were obtained in a mixture of CH(3)OH and THF.
