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.
提出了一种合成几种6-苯乙烯基-1H-吡唑并[3,4-b]喹啉的方法，这些化合物是有前景的光电子材料。特别地，通过沃兹沃思-埃蒙斯反应制备了6-苯乙烯基-1,3-二苯基-1H-吡唑并[3,4-b]喹啉。这些材料的一个优点是其光谱相对于可能的顺反异构化具有稳定性。对苯乙烯基喹啉的光吸收和光致发光激发光谱进行了理论和实验研究。结果表明，与其他方法相比，AM1半经验方法给出了更好的结果。我们发现溶剂对光谱行为没有影响。背面取代基对观察到的光谱没有实质性影响。
