Abstract
A strong and stable room temperature phosphorescence (RTP) emission. was observed from: the ternary inclusion complex of alpha-bromonaphthalene (alpha-BrN)/beta-cyclodextrin (beta-CD)/hexahydropyridine (HHP) without deoxygenation from solution in the presence of micro amount of HHP. The effects of temperature, pH values and the variation of concentrations of each component on RTP had been investigated. Under, the optimal conditions, the analytical curve of alpha-BrN gives a liner dynamic range of 2.0 - 20.0 mu mol/L with a detection limit of 3.7 x 10(-8) mol/L. The experimental results demonstrated that the recovery of the proposed method was 92.4% with a relative standard deviation less than 1.57% (n =7).
