Whereas the complex [Ru(phen)2Medpq]2+
(phen = 1,10-phenanthroline; Medpq = 2-methyldipyrido[3,2-f:2′,3′-h]-quinoxaline) is luminescent in both aqueous and nonaqueous solutions, [Ru(phen)2dpqa]2+
(2-pentylamidodipyrido[3,2-f:2′,3′-h]-quinoxaline) does not emit in water but does so strongly in organic solvents or when bound to DNA—suggesting its use as a photochemical and photophysical probe for nucleic acids.
复合物[Ru(phen)2Medpq]2+(phen =
1,10-菲罗啉;Medpq = 2-甲基二
吡啶并[3,2-f:2′,3′-h]-
喹喔啉)在
水溶液和非
水溶液中都能发光,而[Ru(phen)2dpqa]2+(2-戊酰基二
吡啶并[3,2-f:2′,3′-h]-
喹喔啉)在
水中不发光,但在有机溶剂中或与 DNA 结合时会强烈发光,这表明它可用作核酸的光
化学和光物理探针。
