Poly[(2-cinnamoylethyl methacrylate)-random-(2-octanoylethyl methacryl
ate)]-block-poly(acrylic acid) [P(CEMA-r-OEMA)-b-PAA] forms micelles i
n water with P(CEMA-r-OEMA) as the core and PAA as the shell. POEMA is
incorporated into the micellar cores. After PCEMA cross-linking, POEM
A is extracted to produce porous water-soluble P(CEMA-r-OEMA)-b-PAA na
nospheres. The porous nanospheres sorb a significantly higher amount o
f perylene from water/acetone and water/acetone/DMSO mixtures than the
nonporous P(CEMA-r-OEMA)-b-PAA nanospheres.
