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.
