摘要: Abstract UV/VIS absorption and emission spectra of some polyazomethines containing dihydroxyanthraquinone units siloxane moieties have been investigated in solvents different polarities. The Catalan solvent scale was used for describing the solvatochromic shifts bands. influence composition binary mixtures on solvation maxima studied. following were utilized: methanol-dimethyl sulfoxide (MeOH-DMSO), chloroform-DMSO (CHCl 3 -DMSO) chloroform-methanol -MeOH). preferential parameters local mole fraction (X 2 ), excess function (δ s2 ) constant (K PS determined.
