Study on Terphenyl Isomers by Second-Derivative Solid-Substrate Room Temperature Phosphorescence

ABSTRACT

Terphenyl (TP) isomers p-terphenyl (p-TP) and m-terphenyl (m-TP) were studied by second-derivative solid-substrate room temperature phosphorescence (d²-SS-RTP) with thallous sulfate as a heavy atom perturber and filter paper as substrate. Various factors affecting d²-SS-RTP were discussed in detail. The method for the simultaneous determination of p-TP and m-TP was proposed without any preliminary separation.
