Optical second harmonic images of merocyanine J-aggregate monolayers at the air-water interface
By using the second harmonic generation (SHG) microscope, two-dimensional distribution of SHG-active domains of merocyanine J-aggregates at the air-water interface was successfully observed. It was found that the ionic compound of the subphase strongly influenced the form, size and anisotropy of the SHG-active domains.
