以染料分子BY为酸、碱性探针,研究了含BY的BSF,BY的CTAB胶束溶液和BY水溶液三种微环境,在不同pH条件下的共振Raman光谱。结果表明,束缚于BSF夹心界面和胶束界面的BY,具有类似的光谱变化,但BSF在很大的pH范围内(中-碱性),以酸式和碱式结构共存为特点。进一步研究发现,BSF夹心水核相的pH,对体相pH的变化,表现出相对稳定的新功能。 Resonance Raman spectra of three kinds of microenvironment including BY, BSF, CTAB micellar solution of BY and BY aqueous solution were studied by using dye BY as acid and basic probe. The results show that BY bound to the BSF sandwich interface and micellar interface has similar spectral changes, but BSF is characterized by the coexistence of acidic and basic structures over a wide pH range (mid-alkaline). Further study found that the pH of BSF core-water phase showed a relatively stable new function to the change of pH of bulk phase.
