Abstract:The properties of fluorescence and room temperature phosphorescense (RTP) of 2-Bromomethyl naphthalene (2-BrMN)were studied. The results show that the wavelength for maximum fluorescence of 2-BrMN is lambda(ex/lambda(em) = 274/334 nm. The fluorescence intersity is proportional to the concentration of 2BrMN in the range of 1.0 x 10(-6) - 1.2 x 10(-4) mol x L(-1), and the detection limit is 4.7 x 10(-8) mol x L(-1). The RTP signal of 2-BrMN was induced by beta-cyclodextrin (beta-(CD) in the presence of dibromopropane (DBP) acting as a heavy atom perturbation. The RTP intensity is linear for 2-BrMN/beta-CD/DBP systems of 2-BrMN concentration in the range of 1.0 x 10(-5) - 1.2 x 10(-4) mol x L(-1) (lambda(ex)/lambda(em) = 271/493,521 nm), and the detection limit is 2.7 x 10(-6) mol x L(-1).
Keywords:Bromomethyl naphthalene    Fluorescence    Room temperature phosphorescence
