摘　　要：对β－环糊精（β－ＣＤ）溶液中４种多环芳烃α－溴代萘（α－ＢｒＮ）、β－溴代萘（β－ＢｒＮ）、菲、敏化丁二酮（ＢＩＡＣ）的室温光（ＲＴＰ）进行了研究，β－ＣＤ能有效地增强敏化光强度，并从三重态能量、主客体分子几何尺寸大小等方面讨论了各种因素的影响。方法的线性动态范围上限受能量受体浓度的限制，其检出限达 １０－８ｍｏｌ／Ｌ。This paper reports the biacetyl room temperature phosphorescence(RTP) in β-cyclodextrin (β-CD) system, sensitized by the four polycyclic aromatic hydrocarbons such as a-bromonaphthalene, β－ bromonaphthalene, phenanthrene and chrysene. In this system β-CD can enhance the RTP intensity. Several factors influencing the RTP, e. g., triplet state energy, the size of host and guest, are discussed. The upper foot of linear range of analytical curve is restricted by the concentration of acceptor. The detection limit is 10-8 mol/L.
