The formation of two-dimensional crystalline J-aggregates of a negatively charged water-soluble cyanine dye at a monolayer of a dimethylammonium amphiphile is observed by fluorescence microscopy and spectroscopy. It is demonstrated that domain size and morphology and spectroscopic properties can be controlled via the surface layer. The formation of rod-shaped crystalline aggregates tightly bound to the surface layer is established. These domains are of uniform size and shape, and order due to long-rang electrostatic repulsion.
