Abstract

In this paper, the orientation of thin films of tetra-substituted nickelphthalocyanine NiPcR4 (R = –SCH[CH2(OCH2CH2)2OC2H5]2) deposited between two electrodes is studied by the method of polarized Raman spectroscopy and polarized microscopy. It has been shown that the films of NiPcR4confined between ITO and metal (Al, Au) electrodes are characterized by homeotropic alignment while no homeotropic alignment was observed on ITO substrate with air interface. These findings are very important for the interpretation of electrical conduction through thin films of NiPcR4 in sandwich structures.
