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.

Room-temperature phosphorescence of hydroxyl-substituted aromatics adsorbed on solid surfaces

Journal Article Dalterio, R A ; Hurtubise, R J - Anal. Chem.; (United States)

Several polymer-salt mixtures were examined as solid surfaces for room-temperature phosphorescence (RTP). A variety of hydroxyl-substituted aromatic compounds were observed to give RTP when absorbed on poly(acrylic acid) (PAA)-sodium halide mixtures and filter paper. A solid-sample holding plate was used with a spectrodensitometer for solid surface luminescence detection of components on powder and filter paper adsorbents. RTP analytical data, including linear ranges of calibration curves and limits of detection for several compounds, were compared for 1% PAA-NaBr powder and filter paper.

Solid-matrix luminescence interactions and analytical aspects of phenylphenol isomers on filter paper

Miscellaneous Purdy, B B

The solid-matrix luminescence limits of detection, percent relative standard deviation, and linear concentration ranges were obtained for model compounds adsorbed on four different solid-matrices. Filter paper showed the best analytical merit. Several solid-matrix luminescence properties of phenylphenol isomers adsorbed on Whatman filter paper were investigated. In the presence of sodium halide salts, the luminescence intensity, lifetime, quantum yield and modulus data were obtained to study heavy-atom effects, quenching effects by salts and moisture, and photophysical processes and molecular interactions in the solid-matrix. For 4-phenylphenol, 3-phenylphenol, and 2-phenylphenol, heavy-atom effects were observed for the room-temperature luminescence intensities. The room-temperature phosphorescence wasmore »« less
Determination of room-temperature fluorescence and phosphorescence quantum yields for compounds adsorbed on solid surfaces

Journal Article Ramasamy, S M ; Senthilnathan, V P ; Hurtubise, R J - Anal. Chem.; (United States)

A method for the determination of the room-temperature fluorescence and room-temperature phosphorescence quantum yields for organic compounds adsorbed on different surfaces is described and evaluated. Quantum yield values were determined for compounds adsorbed on sodium acetate, a polyacrylic acid-NaBr mixture, and filter paper. The approach employs conventional instrumentation with various instrumental modifications for obtaining accurate and reproducible data. Quantum yield values at room temperature with and without nitrogen flowing over the solid surfaces are compared. The results show that the method is very reproducible and relatively low quantum yield values can be obtained. 17 references, 1 figure, 3 tables.

Solid surface luminescence analysis. (Progress report) November 1982-March 1984

Technical Report Hurtubise, R J

Several advances were made in understanding the interactions responsible for room-temperature phosphorescence. Infrared data showed that it was possible to obtain strong room-temperature phosphorescence from compounds adsorbed on some surfaces which contained adsorbed water. A partial model for phosphor/solid-surface interactions was developed for nitrogen heterocycles and polycyclic aromatic hydrocarbons adsorbed on poly(acrylic acid)-salt mixtures. It was discovered that hydroxyl aromatics can behave as hydrogen donors, hydrogen accepting species, or as both hydrogen donors and hydrogen acceptors when adsorbed on solid-surfaces. Several new analytical methods and techniques were developed. Poly(acrylic acid)-phosphor solutions that were spotted on filter paper resulted in lowermore »« less
Zeroth and second derivative fluorescence and phosphorescence analysis of mixtures of hydroxyl aromatics adsorbed on filter paper

Journal Article Dalterio, R A ; Hurtubise, R J - Anal. Chem.; (United States)

Recent research activity in the area of luminescence from compounds adsorbed on solid supports has centered around the development of room-temperature phosphorescence (RTP) as an analytical technique. Much of this work is summarized in recent reviews. Filter paper has been the most widely used adsorbent for inducing RTP from aromatic molecules. In addition, considerable work has been reported on room-temperature fluorescence (RTF) analysis of organic compounds adsorbed on solid surfaces. However, there has been only one report of the combined use of solid-surface RTF and RTP for qualitative analysis. One limitation in the use of solid surface RTP and RTFmore »« less
