Electroabsorption and electrophotoluminescence spectra of supramolecular porphyrin dimers in a solid film of poly(methyl methacrylate), PMMA, have been examined. The electroabsorption spectra in the Soret band region are fitted by the deconvolution of the corresponding absorption spectrum into four components, indicating that electroabsorption measurements are useful to identify bands that are hard to distinguish in absorption spectra. The values of the changes in molecular polarizability and dipole moment following photoexcitation are evaluated at each absorption band.
已经检查了聚甲基丙烯酸甲酯(PMMA)固体膜中超分子卟啉二聚体的电吸收和电光致发光光谱。索雷带区域中的电吸收光谱通过将相应的吸收光谱解卷积成四个分量来拟合,这表明电吸收测量可用于识别吸收光谱中难以区分的带。在每个吸收带评估光激发后分子极化率和偶极矩的变化值。
