Morphology transformations of multicompartment assemblies of polystyrene-polyisoprene-poly(2-vinylpyridine), PS-PI-P2VP, was demonstrated. As the solvent quality is continuously varied the triblock copolymer experiences transformations from core-shell-corona micelles to particles with perforated lamellae, or from multicompartment micelles into PI-perforated PS-P2VP lamellae. Such multicompartment...
Crown ether-centered two-armed polymers, i.e., polystyrene-dibenzo-18-crown-6-polystyrene (PSCS) and poly(methyl methacrylate)-dibenzo-18-crown-6-poly(methyl methacrylate) (PMCM), were designed to self-assemble in a proposed manner directed by the specific affinity between the polar crown ether rings. When spin coated onto a silicon wafer surface, macroporous films were obtained. In contrast, the...
Highly ordered honeycomb-like macroporous films were obtained via self-assembly of a two-armed polymer with a crown ether core under controlled conditions. A possible mechanism is speculated, primarily based on the strong affinity between the crown ether cores. The pore size and arrangement are sensitive to the solvent evaporation rate and the solution concentration. Upon spontaneous drying, the pore...
