摘要：

The two-dimensional polar crystallite of amphiphilic merocyanine dye molecules exhibits a thermochromic phase transition on the aqueous subphase. Grazing incident X-ray diffraction measurements were performed onto Langmuir-Blodgett films consisting of the high and/or low temperature phases of the crystallites. It was clarified that the transition accompanies the structural change of the crystallite.
