Correlation coefficient: 0.9962 . Positively charged'free'complex ions should be readily quenched by 〓, but when it is bound to DNA, it can be protected from the quencher because the highly negatively charged 〓 would be repelled by the negative DNA phosphated backbone, hindering quenching of the emission of the bound complex.
从理论上讲,带正电的配合物的阳离子应该可以被大阴离子淬灭,但是在DNA存在下,金属配合物插入到DNA的碱基对中,而〓被带负电荷的DNA磷酸骨架强烈排斥,从而避免了〓的淬灭,因此大的Stern-Volmer曲线斜率相应于对配合物较弱的保护形式。D。
