| Research Abstract |
The orientations of the VOPc plate pressed at 1ton/cm^2 and VOPc thin film produced under Tp : 200ﾟC,Ts : 200ﾟC and te : 190 min by MBE method were investigated by X-ray diffraction. The X-ray diffraction pattern of the VOPc plate pressed at 1ton/cm^2 shows a lot of peaks along diffraction angle. This means that the VOPc plate pressed at 1ton/cm^2 is formed with many random orientation. In the VOPc thin film produced by MBE method, two peaks which are not observed in the X-ray diffraction spectrum for the muscovite subsutrate, markedly exist from these data. This means that the distances between VOPc molecules are estimated as 3 A and 3.8 A.The VOPc molecule is a plane molecule having a triangular structure with 14A as a base line length. These indicate that each molecule in the VOPc thin film is oriented in parallel to the substrate. These results support the existence of strong interaction between VOPc thin film/muscovite interface observed by ESCA.Detailed explanation for the existence of two kinds of parallel orientation on the muscovite is under investigation.
