可溶性酞菁化合物的溶剂效应

Solvent Effects of Soluble Phthalocyanines

通过对所合成的9个可溶性酞菁衍生物在13种不同性质溶剂中吸收光谱的研究,发现其最大吸收波长的波数ν与f(n,ε)具有良好的线性相关性,表明化合物λm ax的位移变化主要由与溶剂折射率n相关的Bayliss函数项所决定,且与溶剂的介电常数ε有关;忽略酞菁分子之间的相互作用(即聚集的影响)以及溶剂的配位能力,是引起模型线性相关性偏差的主要原因.

The results of UV absorption spectroscopy of nine soluble phthalocyanines in thirteen solvents indicated that there is good linearity between the u of the λmax and f（ n, ε） , so the change of λmax are determined by the Bayliss function which is correlating with the refractive index and the dielectric constant of the solvent. In addition, the interaction among the molecules of phthalocyanines and the coordination ability of solvents were the main cause of the calculation error.
