Title: External conditions and interactions in room-temperature phosphorescence of hydroxyl aromatics adsorbed on solid surfaces containing poly(acrylic acid)

Abstract

Poly(acrylic acid)-salt mixtures were studied as solid surfaces for inducing room-temperature phosphorescence from hydroxyl-substituted aromatic compounds so surface interactions and optimal conditions for room temperature phosphorescence could be determined. The mixtures were examined with respect to the type of salt, salt-polymer ratio, acid-base form of the polymer, and ethanol-water volume ratio of the adsorbing solvent. A solution containing 10% water in ethanol, which was used to adsorb 4-phenylphenol onto a poly(acrylic acid)-NaBr mixture, was found to induce enhanced room-temperature phosphorescence intensity. Infrared data indicated that even with water adsorbed on the poly(acrylic acid)-NaBr matrix room-temperature phosphorescence was observed. A comparison of room- and low-temperature phosphorescence intensities was made with several model compounds to estimate the efficiency of room-temperature phosphorescence from the poly(acrylic acid)-salt matrix. In addition, room-temperature phosphorescence was measured as a function of time to determine the effects of atmospheric humidity on the poly(acrylic acid)-salt matrix. Fluorescence polarization was also used to obtain information about phosphor-poly(acrylic acid) binding in ethanol solutions.
