Previously unknown 2-4-aryl-5-cyano-[2,2′-bipyridin]-6(1H)-ylidene}malononitriles were synthesized by reaction of 3-aryl-1-(pyridin-2-yl)prop-2-en-1-ones (azachalcones) with malononitrile dimer. Their colored solutions showed fluorescence in the yellow–orange region with the emission maxima located at λ 565 to 582 nm, depending on the substituent in position 4 of the pyridine ring bearing cyano groups
以前未知的 2-4-aryl-5-cyano-[2,2'-bipyridin]-6(1H)-ylidene}丙二腈通过 3-aryl-1-(pyridin-2-yl)prop- 反应合成2-en-1-ones(氮杂查尔酮)与丙二腈二聚体。它们的彩色溶液在黄橙色区域显示荧光,发射最大值位于 λ 565 至 582 nm 处,这取决于带有氰基的吡啶环第 4 位的取代基。由于2,2'-联吡啶和丁-1,3-二烯-1,1,3-三甲腈片段在其分子中的独特组合,合成的化合物有望作为化学传感器进一步研究。
