合成了不同取代基和不同取代基位置的可溶性氧钒酞菁化合物, 并采用简并四波混频方法测定了这些化合物在非共振条件下的<γ>值和X^(^3^)值, 它们分别在10^-^3^1esu及10^-^1^0~10^-^9esu数量级。酞菁环上取代基的性质将影响化合物的<γ>值, 取代基的给电子能力越强, <γ>值就越大, 而取代基位置对<γ>值的影响较小。

Soluble vanadyl phthalocyanines with different substituents and substituted in different position were synthesized. 10^-^3^1 esu and 10^-^1^0~10^-^9 esu order of magnitude of off-resonant third-order hyperpolarizability <γ> and X^(^3^) values for them were measured, respectively, by degerate four-wave mixing. It is found that the <γ> value is depended on the nature of the substituents. The stronger the electron-donating ability of substituent, the larger the <γ> value. However, the substituting position has only little effect on the <γ> value.

Key words: OPTICAL PROPERTIES, SUBSTITUENT EFFECT, OXYGEN COMPOUNDS, VANADIUM COMPOUNDS, PHTHALOCYANIN (=PHTHALOCYANINE)
