ABSTRACT This study dealt with the reactions of hexachlorocyclotriphosphazatriene, N(3)P(3)Cl(6) (trimer) (1) with phenolphthalein (2) to give the phenolphthalein bridged compounds 3, 4 and 5. The phenolphthalein bridged cyclotriphosphazatriene derivatives are reported for the first time. The new compounds (3-5) are characterized by elemental analysis, mass spectrometry, UV-vis, FT-IR, (1)H, (31)P NMR and fluorescence spectroscopy. The more bridged phenolphthalein groups show the higher intensity of the absorption bands in the UV-vis spectra. Fluorescence spectrum of compound 3 shows a small band in the lower spectral range, while the spectra of compounds 4 and 5 show more intense and a band in higher spectral range.
