It was proposed a method of synthesis several 6-styrylo1-1H-pyrazolo[3,4-b]quinolines as promising material for optoelectronics. Particularly, 6-styryl-1,3-diphenyl-1H-pyrazolo[3,4-b]quinolines were prepared by Wadsworth–Emmons reaction.One of advantageous of these materials is stability of their optical spectra versus the possible cis- and trans-transformation.Theoretical and experimental studies of optical absorption and photoluminescence excitation spectra for styryloquinolines were done. They show that the AM1 semi-empirical method gives better results compared to other approaches. We have found that the solvents do not play a role in the behavior of the spectra. The backside-substituted groups do not influence substantially the observed optical spectra.
