TI  - Self-assembly of acridine orange dye at a mica/solution interface: formation of 
      nanostripe supramolecular architectures.
PG  - 272-9
AB  - Optical waveguide spectroscopy and atomic force microscopy (AFM) have been used 
      to characterize the supramolecular architectures of acridine orange (AO) dye 
      self-assembled at a mica/aqueous solution interface. Under the saturated 
      adsorption conditions, optical waveguide spectroscopy revealed that the dye 
      formed H-type aggregates at the interface. In situ AFM visualized interesting 
      morphology of the dye aggregates showing nanosized meandering stripes with the 
      width of approximately 1.5 nm (or brightness periodicity of approximately 3 nm). 
      Electrostatic adsorption of the dye cations onto a mica surface as well as the 
      intermolecular pi-pi stacking brought about the ordered nanostructures. We 
      propose an interfacial aggregation model that shows a meandering staircase 
      structure with the intermolecular slip angle of 60 degrees. According to the 
      model, the AO molecule occupies a surface area of about 1.0 nm2.
