Abstract

Dewetting of a polymer solution was used to prepare micrometer-sized 'domes' of polymers. Co-casting two different cyanine dyes led to the incorporation of the dyes into the microdomes. Fluorescence microscopy and micro-spectroscopy was used to determine the aggregation state of the dyes within the microdomes. Bleaching experiments revealed that the dyes form hierarchic structures: dye molecules form sub-micrometer J-aggregates, which in turn align at the edge of micrometer-sized domes that form 2-dimensional arrays. Furthermore, it was found that energy migration occurs between different aggregates. [DOI: 10.1380/ejssnt.2005.165]
