Abstract
Ellipsometric and nonlinear optical properties of new, differently substituted, 1,3,5-triphenylpyrazolines dyes, were studied. Results of theoretical calculation within a framework of density functional theory (DFT) technique were verified by spectroscopic ellipsometry and optical second harmonic generation (SHG) experiment at fundamental laser wavelength 1064 nm. Absorption bands and complex refractive indices were determined. Principal role of 2-thienyl substituent for first order nonlinear optical properties was demonstrated.
