TY - JOUR A1 - Thünemann, Andreas A1 - Kubowicz, S. A1 - v. Berlepsch, H. A1 - Möhwald, H. T1 - Two-Compartment Micellar Assemblies Obtained via Aqueous Self-Organization of Synthetic Polymer Building Blocks JF - Langmuir N2 - We synthesized a symmetric linear ABCBA pentablock copolymer consisting of poly(ethylene oxide), poly(-benzyl L-glutamate), and a poly(perfluoro ether) (fluorolink). The different blocks are highly immiscible with each other and form two-compartment micelles of mainly cylindrical shape in aqueous solution with lengths in the range of 100 to 200 nm and diameters of about 24 nm. The poly(perfluoro ether) (C blocks) forms the liquidlike center of the micelles (d = 6 nm). This is surrounded by a first shell of ca. 2 nm thickness consisting of -sheets of poly(-benzyl L-glutamate) (B blocks) and a second 7 nm shell of poly(ethylene oxide) (A blocks). The A blocks provide water solubility, and the B and C blocks form separated hydrophobic compartments. This work is a contribution to the development of multicompartment micelles devoted to mimic transport proteins such as serum albumins in long-term development.
