摘要：

Third-order nonlinear optical susceptibilities chi(3) of tetrakis-n-pentoxy-carbonyl (COO-C5H11) naphthalocyanines containing central metal atom oxovanadium (VO), copper (Cu), zinc (Zn). palladium (Pd), and nickel (Ni) were measured by the third-harmonic generation (THG) technique. The metal atom substitution influences the third-order nonlinear optical susceptibility but the variation is less dramatic; oxovanadium cation was found to be the most effective. The order of chi(3) (-3omega; omega, omega, omega) at 2.1 mum wavelength was VONc > CuNc > ZnNc > NiNc > PdNc. The chi(3)(-3omega: omega, omega, omega) for VONc is 8.6 x 10(-11) esu, more than an order of magnitude larger than those of CuNc, ZnNc, PdNc, and NiNc compounds. A comparative study of optical and nonlinear optical properties of processable metallo-naphthalocyanines is presented.
