摘要
在中性磷酸盐缓溶冲液中，用电化学和荧光光谱法研究了Ｃｕ（ｂｐｙ）２＋２与鸟嘌呤和鸟苷的相互作用。结果表明鸟嘌呤和鸟苷与Ｃｕ（ｂｐｙ）２＋２的配位比均为１∶１，配位常数分别为４．６２×１０４Ｌ／ｍｏｌ和１．９６×１０４Ｌ／ｍｏｌ。紫外光谱电化学实验进一步表明。
The interaction of Cu(bpy) 2+ 2 with guanine and guanosine in phosphate buffer (pH 7 0) was studied by electrochemistry, fluorescence and UV spectroelectrochemistry From the electrochemical and fluorescence data it was obtained that the complex ratio of copper complex to guanine or guanosine was 1∶1, and the complex constants of Cu(bpy) 2+ 2 with guanine and guanosine were 4 62×10 4 L/mol and 1 96×10 4 L/mol, respectively At the same time, the UV spectroelectrochemical features further proved that there was interaction of Cu(bpy) 2+ 2 with guanine or guanosine
