摘要	Both the surfactant and beta-cyclodextrin (beta-CD) had the sensitizing effect on the fluorescence intensities (FIs) of 4-tert-octylphenol (4-t-OP). beta-CD and 4-t-OP could form 1:1 inclusion complex, the association constant was 9.8 x 10(3) L/mol and the change of free energy was -5.44 kJ/mol, indicating that the complex formation of 4-t-OP-beta-CD was thermodynamically favorable. The absolute fluorescence-quenching values (Delta F-a) of the 4-t-OP-ILs system were higher in the presence of beta-CD (Delta F-a, 113-144 a. u.) than those (Delta F-a, 28-33 a.u.) in the absence of beta-CD, suggesting the sensitizing effect of beta-CD on 4-t-OP-ILs quenching system. With the addition of ILs, the included probabilities of 4-t-OP by beta-CD were greatly decreased, leading to the weakly protecting effects of beta-CD from the collision quenching of 4-t-OP molecules in aqueous solution, and thus the FIs of 4-t-OP-beta-CD were markedly quenched. The bimolecular quenching constants (K-q) by four ILs were all less than 2.0 x 10(10) L/mol, and the fluorescence lifetimes (FLs) of 4-t-OP-beta-CD ranged from 4.86 to 3.15 ns in ILs concentration range of 0-0.6 mM. Based on the consistent interpretations from FL, FI and temperature effect data, it can be concluded that the quenching mode of 4-t-OP-beta-CD system by ILs is a dynamic quenching mechanism. The results obtained in this study lay theoretical foundation for the detection of trace 4-t-OP or ILs by means of the sensitizing fluorescence-quenching method. (C) 2014 Elsevier B.V.
