Abstract

Four techniques for inducing room temperature phosphorescence (RTP) in fluid solution are discussed, and the general requirements of molecular association for observation of RTP are presented. These methods are micelle-stabilized RTP, microcrystalline/colloidal RTP, cyclodextrin-induced RTP, and sensitized/quenched RTP. Examples of results using the different techniques for several classes of molecules, including carbocyclic and heterocyclic aromatic hydrocarbons and drugs, are used to illustrate the capabilities of these methods. The analytical utility of the four methods is compared and contrasted.
