Cross-linked conjugated polymer assemblies at the air-water interface through supramoleculer bundling

We demonstrated conjugated polymer assemblies formed by coordination interaction with a porphyrinatozinc cross-linker at the air-water interface by means of the Langmuir-Blodgett technique. The coordination bonds were maintained at the interface, though the spacing between the polymer backbones in the Langmuir film was smaller than that in bulk solution, probably because of the influence of the interface. The successful transfer of the films to a substrate enabled the fabrication of a large-scale conjugated polymer material.
