An amphiphilic penta-telechelic polyhedral oligomeric silsesquioxane (POSS)-containing inorganic/organic hybrid poly(acrylic acid), (Glu-PAA-POSS5), is prepared by hydrolysis of penta-telechelic poly(tert-butyl acrylate) (Glu-PtBA-POSS5), synthesized by the combination of atom transfer radical polymerization (ATRP) and a click reaction. The self-assembly behavior of Glu-PAA-POSS5 in aqueous solution at pH 8.5 is investigated by using transmission electron microscopy (TEM), scanning electronic microscopy (SEM), atomic force microscopy (AFM), and dynamic light scattering (DLS). The results show that Glu-PAA-POSS5, with a long poly(acrylic acid) (PAA) chain, can self-assemble in water into giant capsules, which provides an optional approach in the construction of capsules. <boxed-text content-type="graphic" position="anchor"> <graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="urn:x-wiley:10221352:media:macp201400012:macp201400012-abs-0001">image</graphic
