The method of polarography used for measuring half-wave potential of the cyanine dye is one of the important ways in studying the spectral sensitization property of dye. 用极谱分析法测定光谱增感染料的半波电位是研究染料增感性能的重要方法之一。
Under the same condition, the half-wave potential of 2-methyl substituted compound is ca. 120 mV lower than the unsubstituted one. 苯环上引进二个甲基取代基,其相应的苯胺化合物的半波电位下降大约120mV。
The oscilloscope polarography method for determining the half-wave potential has been mainly investigated. 本文主要研究用示波极谱法测定菁染料的半波电位。
The electronic levels and the lowest excitation energy of triplet state of the organic conjugated molecules, as well as the half-wave potential of some sensitizing dye molecules were evaluated using PPP and CNDO/ 2 methods. 应用CNDO/2方法和PPP方法计算了有机共轭分子的电子能级、最低三重态激发能及增感染料分子的半波电位。
The resonance integral β was evaluated with linear regressive analysis. Values of excited energies and reduction half-wave potential of these dyes were paralleled with each other, being in complete agreement with the published experimental data. 用线性回归分析方法确定了交换积分β,由此得到的染料分子的激活能和还原半波电位值均与实验数据符合得很好。
