Abstract

The absorption and fluorescence spectroscopic studies on the interaction between thionine (TH) and sodium dodecyl sulfate (SDS) have been carried out. The absorption and fluorescence spectral changes of TH with the changes of concentration of SDS are interpreted in terms of i) the aggregation of TH-SDS complex, ii) the stacking process of dye molecules by the association of the TH-SDS complex, iii) breakdown of the stacking due to the formation of dye-rich induced micelles, iv) redistribution of dye molecules in the surface of SDS micelles.

Sodium dodecyl sulfate (SDS) 존재하에서 유기색소인 thionine (TH)의 흡수 및 형광분광학적 성질을 조사 연구하였다. SDS 농도 증가에 따라 측정한 흡수 및 형광스펙트럼의 변화들로부터 i) TH-SDS 착화합물의 회합체 형성, ii)TH-SDS 회합체내의 색소분자의 stacking 과정, iii)dye-rich induced micelles의 형성에 의한 staking의 파괴 및 iv) SDS 미셀의 표면에 TH의 재분포과정 등으로 설명하였다.
