摘　　要：合成了四叔丁基碘代萘酞菁镓((t-Bu)4NcGaI)化合物,利用元素分析、红外光谱、核磁共振氢谱等方法,验证了化合物的分子结构。该化合物的Q带在近红外区(801 nm),相对酞菁化合物红移了70 nm。应用调Q倍频纳秒/皮秒Nd∶YAG脉冲激光,在波长为532 nm,脉冲宽度为4.5 ns,重复频率为2 Hz,脉冲能量39.8μJ的条件下,测试了浓度为1.22×10-4mol/L化合物CH2Cl2溶液的Z-扫描曲线。测得它的非线性折射率n2和三阶非线性极化率χ(3)分别为2.54×10-11esu和9.51×10-12esu。由此计算化合物分子极化率γ′为3.3×10-29esu。The tetra-tert-butylnapbthalocyaninagallium iodine （ （t-BU）l NcGal） was synthesized. The structure of the compound was tested by elementary analysis, infrared spectrum and hydrogen nuclear magnetic resonance spectrum. Q band of the compound is in the near infrared region （801 nm）, red shift about 70 nm compared with phthalocyanine. Z-scan curve of dichlromethane solution of the compound with the concentration of 1.22× 10^4 mol/I, was tested by using a frequency-doubled Qswitched Nd： YAG laser with 4.5 ns laser pulse, repeated frequency of 2 Hz and pulse energy of 39.8 /μJ at the wavelength of 532 nm. The nonlinear refracting index, 71e and the third-order nonlinear polarizability, X^（3） were 2.54 × 10^-11 esu and 9.51 5〈 10^-12 esu, respectively, so the molecular polarizability γ＇ of the compound was 3.3×10^-29 esu.
