The simultaneous, segregated storage of two different chromophores in a multicompartment micelle, which is formed from self-assembly of (polyethylethylene)(polyethylene oxide)(polyperfluoropropylene oxide) mikto-arm star terpolymers in water, was investigated by spectrophotometry. The multicompartment micelles, with segregated micellar cores composed of fluorocarbon and hydrocarbon compartments, can simultaneously absorb two chemically different molecules. These two molecules were confined into their preferred compartments with high selectivity.
