摘要/Abstract

摘要： 测定了一系列偶氮香豆素化合物的紫外吸收波长(λ_a)、摩尔吸光系数(ε)和最大荧光发射波长(λ_e)的数据,并用溶致变色法测算了它们的二阶非线性极化率(β_xxx).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.

关键词: 偶氮香豆素, 二阶非线性极化率, 溶致变色法

Abstract: The maximum absorption wavelength (λ_a),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.

Key words: azocoumarin, second-order nonlinear polarizability, solvatochromic method
