Abstract
Poly(dimethylsiloxane) gels containing different amounts of cholestery l anthraquinone-2-carboxylate (CAQ), used as a gelling agent, have bee n prepared and the phosphorescence spectra of CAQ contained in the gel s were measured at 77 K. Two forms of CAQ, free and crystalline, were identified through the phosphorescence measurements, and the relative amounts were determined. It is shown that the relative amount of cryst alline CAQ in the gel decreases with decreasing bulk CAQ content.
