Fluorescence Line Narrowing Spectrometry: Applications to Polynuclear Aromatic Compounds in Organic Glasses

摘要

The versatility of fluorescence line narrowing spectrometry (FLNS) of polynuclear aromatic compounds (PAC) in organic glasses is demonstrated. Fluorescence line narrowed (FLN) spectra of naphthalene, 1-methylnaphthalene, 2-methylnaphthalene, 1-aminonaphthalene, 2-aminonaphthalene, 1,5-diaminonaphthalene, fluorene, 2-aminofluorene, 2,7-diaminofluorene, benzo(a)pyrene-7,9,9,10-tetrahydrotetrol, benzo(a)pyrene-7,8-dihydrodiol-9,10-epoxide(BPDE)-guanosine, BPDE-DNA, and 9-methoxybenzo(a)pyrene-4,5-dihydrodiol were obtained. The FLN spectra of these molecules are well-resolved and characteristic of the chromophore. Resolution of simple mixtures is demonstrated using selective laser excitation. (ERA citation 09:016972)
