摘要
本文报道了N,N′一二甲基硫代花菁染料与十二烷基硫酸钠水溶液体系的电子吸收光谱和荧光光谱,应用Kasha的分子激子理论讨论了光谱特征与染料聚集状态的联系,给出了这一体系中分子聚集状态变化的清晰图象。
Electronic absorption and fluorescence spectra of an aqueous solution of sodium lauryl sulfate (SLS, 2) and N, N'-dimethylthiacyanine iodide (DMTC, 1) over a wide concentration range were recorded. Molecular aggregate states were characterized by [SLS]-dependent change of spectral feature with the aid of Kasha's molecular exciton theory. The 1-2 salt was formed and condensed in a highly aggregate state below the cmc of 2, and was dissolved after the formation of 2 micelle.
