通过卟啉配合物Meso-四(4-羧基苯基)卟啉铜(简称Cu(Ⅱ)-TCPP)中的羧基与γ-氨基丙基三乙氧基硅烷(NH2(CH2)3Si(OC2H5)3,KH550)中的氨基的相互化学作用,成功地把卟啉配合物接枝到KH550中,随着KH550中乙氧基的水解与聚合反应的进行,卟啉铜连接到固体介质中,从而大幅度提高了卟啉在无机固体介质中的掺杂浓度.将反应产物与γ-(2,3-环氧丙氧基)丙基三甲氧基硅烷(CH2CHCH2O(CH2)3Si(OCH3)3,KH560)相杂化,形成物化性能良好、连接卟啉的有机-无机复合材料.用红外光谱表征了Cu(Ⅱ)-TCPP与KH550的化学反应产物,用紫外—可见吸收光谱研究Cu(Ⅱ)-TCPP的分子状态.应用Z扫描技术研究不同Cu(Ⅱ)-TCPP掺杂浓度的复合材料的非线性光学性质,其三介非线性折射率n2达-1.1161×10-16m2/W.
(NH2 (CH2) 3Si (OC2H5)) group by the carboxyl group in the porphyrin complex Meso-tetrakis (4-carboxyphenyl) porphyrin copper (Cu (II) 3, KH550), the porphyrin complex was successfully grafted into KH550. With the hydrolysis of the ethoxy group in KH550 and the polymerization reaction proceeding, the porphyrin copper was connected to the solid medium so that The doping concentration of porphyrin in inorganic solid medium is greatly increased.The reaction product is reacted with γ- (2,3-epoxypropoxy) propyltrimethoxysilane (CH2CHCH2O (CH2) 3Si (OCH3) 3, KH560) to form the organic-inorganic composite with good physicochemical properties and connectivity with porphyrin.The chemical reaction products of Cu (Ⅱ) -TCPP and KH550 were characterized by FTIR spectroscopy and the UV-Vis absorption spectra were used to study the chemical reaction of Cu (Ⅱ) The molecular state of TCP-ZCP was studied by using Z-scan technique. The nonlinear optical properties of composites with different concentrations of Cu (II) -TCPP were studied. The refractive index n2 of matrix was -1.1161 × 10-16m2 / W.
