Solvatochromism and electrophilicity
Chemical Physics Letters, 2011 Abstract Solvatochromic dyes that exhibit a negative or a positive behaviour may be distinguished and their solvatochromism predicted with the aid of DFT-based indices, such as their electrophilicity ω , hardness η and by the Fukui electrophilic functions f G + of the donor and acceptor moieties of the molecule, calculated in the ...

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