摘要:

β-cyclodextrin(β-CD) supramolecular system has been widely utilized in many fields including environmental chemistry, food industry, pharmaceutical chemistry etc. In the area of analytical chemistry, Liu Chang-Song and coworkers established p-cyclodextrin induced room temperature phosphorimetry(CD-RTP) by chemical deoxygenating technique. Guest molecules are complexed and rigidified by the hydrophobic cavity of β-CD, enhanced RTP emission can be observed after the solution is deoxygenated. Bromocyclohexane contains the bulky hydrophobic cyclohexyl and heavy atom bromide, it is an ideal perturber molecule. In this paper, β-CD/phosphors/Bromocyclohexane supramolecular system is utilized to determine four polycyclic aromatic hydrocarbons(PAHs) such as acenaphthene, fluorene, phenanthrene,7,8-benzoquinoline.
