The use of room-temperature phosphorescence (RTP) for the selective analysis of nitrogen-containing heterocyclics has been investigated. The RTP emissions of azaarenes are enhanced in the presence of mercury(II) chloride, while those of homocyclic polyaromatic hydrocarbons (PAHs) are quenched. The combined use of Hg(II) as a selective quenching agent and heavy-atom perturber in the RTP detection of selected nitrogen-containing compounds in the presence of interfering PAHs is reported. Various photophysical aspects of the heavy-atom effect on RTP are discussed based on spectral studies. 24 references, 4 figures, 4 tables.
