Cyclodextrin induced room temperature phosphorescence of some polyaromatic hydrocarbons and nitrogen heterocycles in the presence of cyclohexane
Room temperature phosphorescence (RTP) of some polyaromatic hydrocarbons (PAHs) and nitrogen heterocycles (NHC) can be induced in the β-cyclodextrin cyclohexane (CD/CH) system. RTP spectra characteristics of these compounds in the system are investigated. Different actions for cyclohexane and bromoalkane in β-cyclodextrin induced RTP are suggested. In the CD/CH system the limits of phenanthrene and 7,8-benzoquinoline may reach 2.3 × 10−7 M and 4.5 × 10−7 M, respectively. The relative standard deviation (RSD) is less than 7.6%.
