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

open access: yesIranica Journal of Energy and Environment, 2012
Solvatochromic properties of a series of bis(3–substituted derivatives of acetylacetone) copper(II) (X-acacH , X = Cl, H. CH3) complexes were studied. All the complexes demonstrated negative solvatochromism.
