afforded 6- and 4-(1,2,3-triazol-4-yl)substituted nicotinonitriles in 44–78% yields, possessing pronounced fluorescent properties. The quantitative characteristics of fluorescence were assessed, the relationship between the nature of substituents and the position of absorption and fluorescence bands was revealed.
1,2,3-三唑查耳酮、丙二腈和醇钠的三组分缩合得到 6-和 4-(1,2,3-三唑-4-基)取代的烟腈,产率为 44-78%,具有显着的荧光特性。评估了荧光的定量特性,揭示了取代基的性质与吸收和荧光带位置之间的关系。
