在β-环糊精(β-CD)溶液中,加入阴离子表面活性剂(AS)可诱导1-溴萘(1-BrN)发射强的室温磷光(RTP).组成测定表明溶液中形成了稳定的1:1:1/1-BrN:β-CD:AS三元包合物.光谱和溶液表面张力分析显示阴离子表面活性剂的疏水性烷基链有一部分被包合在β-CD空腔内,未被包合部分则绕曲在β-CD腔口处从而为空腔内1-BrN分子的磷光提供了有效保护.因该三元包合物带有阴离子极性头基,其沉淀可均匀分散在溶液中,形成了稳定的乳状液.得到了稳定的RTP.
The addition of anionic surfactant (AS) to β-cyclodextrin (β-CD) induced strong room-temperature phosphorescence (RTP) of 1-bromonaphthalene (1-BrN) emission.The compositional measurements showed that the solution formed a stable Of the 1: 1: 1/1-BrN: β-CD: AS ternary inclusion complex.Spectral and solution surface tension analysis revealed that the hydrophobic alkyl chain of the anionic surfactant was partially encapsulated in the β-CD cavity , The uncoated portion provides an effective protection for the phosphorescence of the 1-BrN molecule in the cavity by bending around the β-CD cavity. Since the ternary inclusion compound has an anionic polar head group, its precipitate Can be uniformly dispersed in the solution to form a stable emulsion. A stable RTP was obtained.
