| Zusammenfassung: | Zn(II) tetraphenylporphyrin (ZnTPP)-intercalated dialkyl ammonium smectite was applied to the condensation and detection of chlorophenols in aqueous medium. ZnTPP and p-chlorophenol found to form a stable porphyrin-quinone dyad in micelles of dialkyl ammonium ion, accompanied with color-change and fluorescence quenching of ZnTPP. As a result, sub-ppm to ppm order of p-chlorophenol in water can be detected by the fluorescence quenching. |
