The absorption bands of the charge transfer complexes between nucleic acid, purine components and some of their derivatives (9CH3--Ade, Ado, dAdo, pA, App, Guo, Gpp, Gppp, Cof, Hyp) as electron donors and p-benzoquinone as the acceptor were obtained by the differential method in water solution at 293 K. These bands lie in the range 330--430 nm and have all characteristic properties of the charge transfer bands. All points of the relationships between the energy corresponding to the charge transfer band maximum (hvct) and the donor ionization potential (Id) for the nucleic acid components and their derivatives fall on the same straight line for the pi-donors (the aromatic molecules), known from literature data, which differ markedly from the same straight line for n-donors (the alifatic amines), obtained in this work. It shows that the investigated nucleic acid components and their derivatives are the pi-donors in the charge transfer complexes with p-benzoquinone.
在293K的水溶液中，通过微分法获得了核酸、嘌呤成分及其一些衍生物（9CH3--腺嘌呤、腺苷、脱氧腺苷、磷酸腺苷、二磷酸腺苷、鸟嘌呤、二磷酸鸟苷、三磷酸鸟苷、辅酶F、次黄嘌呤）作为电子供体与对苯醌作为受体之间电荷转移复合物的吸收带。这些吸收带位于330-430nm范围内，具有电荷转移带的所有特征性质。对于核酸成分及其衍生物，对应于电荷转移带最大值的能量（hvct）与供体电离势（Id）之间关系的所有点，对于π供体（芳香族分子）落在同一条直线上，这是从文献数据中已知的，与本工作中获得的n供体（脂肪族胺）的同一条直线明显不同。这表明所研究的核酸成分及其衍生物在与对苯醌形成的电荷转移复合物中是π供体。
