This study investigates the enhancement of room-temperature phosphorescence (RTP) for anthracene when the compound is adsorbed on cyclodextrin (CD)-treated filter paper. The results show that ..beta..-CD treatment induces a significant increase in anthracene RTP emission, which is normally extremely weak. The ..cap alpha..-CD does not produce any strong RTP enhancement, while ..gamma..-CD produces relatively lower enhancement than does ..beta..-CD. The CD treatment procedure is very simple and improves the analytical usefulness of the RTP method. The binding constants of anthracene to cyclodextrin were measured with the use of thin-layer chromatographic retention values. Anthracene has a higher binding constant with ..beta..-CD than with ..gamma..-CD, in agreement with the RTP enhancement results.
