Abstract
It could be shown that by a simple casting process from solution two-dimens ionally ordered arrays of mesoscopic (i.e., in the range of submicrometer t o micrometer) polymer aggregates on solid substrates can be formed. Pattern s were investigated by optical microscopy and atomic force microscopy. The pattern formation was observed in situ by optical and fluorescence microsco py and it was found that a "fingering instability'' at the three-phase-line of a solution droplet is the crucial process for pattern formation.
