Abstract The phenanthroline derivatives, which have alkynyl groups, were synthesized by palladium-catalyzed, Sonogashira cross-coupling reaction to provide the following coupled products: 4,7-bis(4-phenylethynyl-phenyl)-[1,10]phenanthroline (6a) and 4,7-bis4-(4-hydroxy-buty-1-ynyl)-phenyl)-[1,10]phenanthroline (6b) at 87 and 89% yield, respectively. Their ruthenium complexes, tris4,7-bis(4-phenylethynyl-phenyl)-[1
摘要 通过钯催化的 Sonogashira 交叉偶联反应合成了具有炔基的菲咯啉衍生物,得到以下偶联产物:4,7-双(4-苯基乙炔基-苯基)-[1,10]菲咯啉 (6a ) 和 4,7-双4-(4-羟基-丁-1-炔基)-苯基)-[1,10] 菲咯啉 (6b) 的产率分别为 87% 和 89%。它们的钌配合物,三4,7-双(4-苯基乙炔基-苯基)-[1,10]菲咯啉}钌(II)双(六氟磷酸盐)(7a)和三[4,7-双4-(4) -羟基-丁基-1-炔基)-苯基)-[1, 10]菲咯啉}钌(II)双(六氟-磷酸) (7b),在温和条件下合成。前者在完全氧化和完全脱氧的气氛之间显示相对荧光强度变化,而后者在 pH 6 和 13 之间显示线性荧光强度响应。
