PPH was oxidized to a red compound (PPH') in the presence of K<jats:sub>2<\/jats:sub>S<jats:sub>2<\/jats:sub>O<jats:sub>8<\/jats:sub>. Interestingly, the room temperature phosphorescence (RTP) of Rhod 6G<jats:sup>+<\/jats:sup> was quenched because the \u2010OH of PPH\u2032 reacted with \u2010COOC<jats:sub>2<\/jats:sub>H<jats:sub>5<\/jats:sub> of Rhod 6G<jats:sup>+<\/jats:sup>\u2013PPH to form Rhod 6G<jats:sup>+<\/jats:sup>\u2013PPH\u2019 and PPH, which decreased the \u03c0\u2010electron density (\u03b4) of the carbon atom in the Rhod 6G<jats:sup>+<\/jats:sup>\u2013PPH\u2019 conjugated system and enhanced the nonradiation energy loss of the excited Rhod 6G<jats:sup>+<\/jats:sup> of the triplet state. The PPH content was directly proportional to the \u0394<jats:italic>I<\/jats:italic><jats:sub>p<\/jats:sub> of the system. Thus, a new catalytic solid\u2010substrate room temperature phosphorimetry (SSRTP) method was established for the determination of PPH. The method had high sensitivity (the limit of detection was 0.019\u2009fg\/spot, corresponding to a concentration of 4.8\u2009\u00d7\u200910<jats:sup>\u201314<\/jats:sup>\u2009g\/mL; the sampling quantity was 0.40 \u03bcL\/spot), good selectivity, convenience and speed. The analytical results were in accordance with those of high\u2010performance liquid chromatography (HPLC). The structures of Rhod 6G<jats:sup>+<\/jats:sup>, PPH and Rhod 6G<jats:sup>+<\/jats:sup>\u2013PPH were characterized by infrared spectra. The reaction mechanism by which PPH was determined is discussed.
