title: Polymeric cyanide azo compounds dipole moments and photo-physical properties in solvents media.
abstract: A quantitative study of solvent environment effects on the photo-physical properties of a group of polymeric cyano azo benzene compounds was carried out at room temperature. Absorption and emission spectra of this group of azo matter with similar structure and different statistical weight of azo block have been studied in different solvents. The solvatochromic method was used to estimate the dipole moments in ground and excited states. The nature and degree of solvent-solute interactions were characterized using Kamlet-Abboud-Taft multi-parameter polarity scale.
