compact and negatively charged acceptor group, N‐(cyanamino)sulfonyl, is introduced for dye design and its influence on the absorption and emission spectra of the “push–pull” chromophores is demonstrated with 1,3,6‐tris[(cyanamino)sulfonyl]‐8‐aminopyrene. The new sulfonamides, including O‐phosphorylated (3‐hydroxyazetidine)‐N‐sulfonyl, are negatively charged electron acceptors and auxochromes. 1‐Aminopyrenes
引入了一个紧凑且带负电荷的受体基团N-(氰氨基)磺酰基进行染料设计,并用1,3,6-tris [(cyanamino)证明了其对“推挽”生色团的吸收和发射光谱的影响。 )磺酰基] -8-氨基py。新的磺酰胺,包括O-磷酸化的(3-羟基氮杂环丁烷)-N-磺酰基,是带负电的电子受体和辅助色素。用新的磺酰胺修饰的1-氨基py烯具有3或6个负电荷(pH≥8),m / z低比率,电场中的高迁移率以及黄色到橙色发射。我们通过还原胺化标记了麦芽糖糊精低聚物,通过电泳分离了产物,并在商业DNA分析仪中证明了它们的高亮度以及发射信号在检测通道之间的分布。
