Fifty-five organic compounds of various sizes and functionalities were investigated for solid-surface room-temperature fluorescence (RTF) and phosphorescence (RTP) on an 80% ..cap alpha..-cyclodextrin-NaCl matrix. Forty-two of these compounds showed either RTP and/or RTF on this matrix. The relative RTP intensities of the compounds were compared, and the results showed that triphenylene gave the strongest RTP signal, while phenanthridine gave the weakest signal. The range of the RTP limit of detection of the phosphorescent compounds on an 80% ..cap alpha..-cyclodextrin- NaCl mixture was determined to be between 0.2 ng and 15 ng. The results showed the general analytical potential of this approach because of the large number of compounds yielding luminescence signals and the selectivity and sensitivity achieved.
