摘　　要：测定了一系列偶氮香豆素化合物的紫外吸收波长(λa)、摩尔吸光系数(ε)和最大荧光发射波长(λe)的数据,并用溶致变色法测算了它们的二阶非线性极化率(βxxx).结果表明,所测定的化合物在溶液状态下表现出较强的二阶非线性极化特性.The maximum absorption wavelength (λ_e),absorption coefficient (ε),maximum emission wavelength (λ_e) of azocoumarin compounds were measured,at the same time,the second-order nonlinear polarizabilities (β_(xxx)) of these compounds were determined by solvatochromic method.The results show that these compounds have high values of second-order nonlinear polarizability in solution.
