Solvatochromism Study on the Copper(II) Complexes Containing 3–Substituted Derivatives of Acetylacetonate Ligands

Solvatochromic properties of a series of bis(3–substituted derivatives of acetylacetone)copper(ii) (x-acach , x = cl, h. ch ) complexes were studied. all the complexes demonstrated negative solvatochromism.3 among the complexes the cu(cl-acac) , demonstrated the most solvatochromism. a multi-parametric equation2 has been utilized to explain the solvent effect on the d-d transition of the complexes using spss/pc software. the stepwise multiple linear regression (smlr) method demonstrated that the donor power of the solvent plays the most important role in the solvatochromism of the compounds.
