Effect of Small Organic Molecules on the Room Temperature Phosphorescence of Ternary Complexes of Two Naphthols

详细研究了９种有机小分子对两种萘酚三元包络物β－环糊精（ＣＤ）／萘酚／１，２－二溴乙烷（ＤＢＥ）室温■光（ＲＴＰ）强度及■光寿命的影响。对比了各种有机小分子对包络于β－ＣＤ中两种萘酚ＲＴＰ的增敏、增稳作用及分析特性。

In this paper, the effect of nine small organic molecules on the room temperature phosphorescence (RTP) of ternary complexes of 1-naphthol and 2-naphthol was studied in detail. The experimental results show that small organic molecules can change the polarity of micro-circumstances of β-CD cavity and increase the RTP intensity and lifetime of naphthols. By addition of methanol, ethanol, n-propanol or 2-propanol, the linear dynamic range of 1-naphthol is extended. The detection limit of 1-naphthol decreases from 4 × 10- 6 mol/L to 7. 5 × 10-8 mol/L when methanol is added and that of 2-naphthol deceases from 2 × 10- 6 to 2. 8 × 10-7 mol/L when glycol is added.
