Abstract

In this study, peripherally tetra-{2-[[4-((E)-{[4-dimethylamino)phenyl]imino}methyl)phenyl](methyl)amino]ethoxy} substituted cobalt(II), manganese(III), copper(II) phthalocyanines 2a-2c and axially di-{2-[[4-((E)-{[4-(dimethylamino)phenyl]imino}methyl)phenyl](methyl)amino]ethoxy} substituted silicon phthalocyanine 3 were synthesized for the first time. These compounds were characterized by standard spectroscopy methods. Their nonlinear optical properties are evaluated with the help of z-scan technique. Both open and closed aperture configurations show clear z-scan signal in the four samples. The refractive nonlinear index n(2) is found to be ranging between -4.9 and -28.1 x 10(-8) cm(2)/W, and the nonlinear absorptive coefficient varied between 0.2 and 5.4 x 10(-3) cm/W. The optical limiting measurements showed low threshold levels, 645 W/cm(2) in 2c and 680 W/cm(2) in 2a in full agreement with Z-scan measurements.
