Copper metalloporphyrin was bonded to 3-aminopropltriethoxysilane (NH2(CH2)3Si(OC2H5)3, KH550) by the chemical reaction between the carboxyl group of Cu(Ⅱ) meso-Tertra(4-carboxyphenyl)porphine (Cu(Ⅱ)-TCPP) and amino-group of KH550. The copper metalloporphyrin was connected to gel network after the hydrolysis and condensation of the product. The reaction product of different concentrations was hybridized with 3-glycidoxypropltrimethoxysilane (CH2OCHCH2O(CH2)3Si(OCH3)3, KH560) with sol-gel processing to form sol-gel inorganic material, which has good physical-chemical and optical properties. The cross-linkage of Cu(Ⅱ)-TCPP and KH550 was estimated and confirmed with FT-IR spectroscopy. The state of metalloporphyrin molecules was investiaged by UV/VIS spectra. It was found that the Cu(Ⅱ)-TCPP exists mainly in the state of monomer. Nonlinear optical properties of samples was studied by Z-scan technique using Ti:Sapphire femto-second laser pluses. The nonlinear refractive index n2 reached -1.1161×10-16 m2/W.
