The effect of anionic surfactant sodium dodecyl sulfate (SDS) on the fluorescence of -B₁₈H₂₂ was studied. The experimental result revealed that the fluorescence of -B₁₈H₂₂ was obviously enhanced with the increase of the concentration of SDS, mainly due to the hydrophobic protection of -B₁₈H₂₂ by SDS. Under the optimum conditions, the fluorescence intensity was proportional to the concentration of -B₁₈H₂₂ in the range of 0-8.0×10⁻³ mol·L⁻¹ and 8.0×10⁻³ mol·L⁻¹-3.3×10⁻² mol·L⁻¹, respectively. It was observed that a break appeared in the curve of fluorescence intensity with surfactant concentration. The critical micelle concentration (CMC, 7.9×10⁻³ mol·L⁻¹) of SDS was obtained from this break point in a good agreement with the reported value. The fluorescence intensity increased initially with time and gradually stabilized. The results form the basis for further study of the properties and application of -B₁₈H₂₂ in SDS solutions.
