摘　　要：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^(-31)esu及10^(-10)～10^(-9)esu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. 10-31 esu and 10 10 ~ 10-9esu order of magnitude of off - resonantthird-order hyperpolarizability <γ> and x(3) values for them were measured, respectively, bydegerate four-wave mixing. It is found that the <γ> value is depended on the nature of thesubstituents. 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.
