磺化金属酞菁的溶剂效应

文章测试了5种磺化金属酞菁在7种不同极性溶剂中的吸收光谱,用N icol理论研究了金属酞菁染料的溶剂效应。实验和理论结果表明,此类化合物最大吸收峰的波数与函数f(n,ε)存在良好的线性关系,线性相关系数都在0.93以上;而Bayliss函数项(n2-1)/(2n2+1)决定了最大吸收波长(λm ax)的位移变化,λm ax总体上随着溶剂折射率的增大而蓝移,随着溶剂极性的增强而红移。基于此结果,提出了通过选择合适的溶剂调节酞菁染料吸收峰的有效方法,从而使酞菁染料更好地应用于激光防护。

Solvent Effects of Sulfonated Phthalocyanine

The absorption spectra of five sulfonated phthalocyanines in seven different solvents are measured,and the solvent effects of phthalocyanines are investigated using Nicol theory.It is found that the maximum absorption wavelength(λ_(max)) of the phthalocyanine compound is linearly dependent on the function f(n,ε),the correlation coefficient is greater than 0.93,and it is mainly related to Bayliss function.The maximum absorption wavelength(λ_(max)) has a tendency of blue shift with the increase of refractive index of solvent,while a tendency of red shift with the increase of solvents polarity.Based on these results,an efficient method of choosing proper solvent to adjust the λ_(max) of the phthalocyanine compound is put forward,so that the phthalocyanine compounds can be better applied in laser protection.
