fig2 as a result a film was prepared in which the resulting copper tetra t butyl phthalocyanine iodide was oriented in the direction of 34 a 34 of fig2 the film was observed by exposing it to a linear polarized light which had the plane of polarization perpendicularly and parallel to the shear direction as a result it exhibited a light yellowish color when it was exposed to the linear polarized light in parallel and it exhibited a dark bluish color when it was exposed to the linear polarized perpendicularly fig3 illustrates the spectra of the transmitted light which the film exhibited during the parallel and perpendicular exposures it exhibited high dichroic ratios of 3 7 9 4 and 4 5 at 500 mm 600 mm and 700 mm respectively as can be seen from fig4 it exhibited the scattering peaks of 110 and 170 cm 1 which resulted from the i 3 ion and the i 5 ion in the crystalline complexes respectively in both of the 34 a 34 axis and 34 b 34 axis directions however it exhibited the scattering peaks larger in the 34 a 34 axis direction than it did in the 34 b 34 axis direction the phthalocyanine molecule exhibits an anisotropy in the absorbance of visible light and accordingly it exhibits a large absorption constant in the direction of the molecular plane as illustrated in fig1 c on the other hand the poly iodine ions.
