Abstract

In the current work, di- and tetra- aniline substituted cyclotriphosphazene derivatives ( 1a-b ) were prepared from commercially available cyclotriphosphazene and underwent nucleophilic substitution reaction with 9-ethyl-9H-carbazol-3-ol ( 2 ) to produce three new cyclotriphosphazene compounds having two- ( 3a ), three- ( 4b ) and four-carbazole units ( 5b ), respectively. The full characterization data of the targeted compounds were obtained by utilizing elemental analysis, mass spectrometry, 1 H, 31 P NMR spectroscopies and also molecular structure of compound 3a was illuminated by single crystal X-ray diffraction technique. As the photophysical aspect of the synthesized compounds 3a , 4b and 5b , UV/vis and steady-state fluorescence spectroscopies were used in different organic solvents. In addition, time-resolved fluorescence, and 3-D fluorescence spectroscopies were applied to get deeper information about the photophysical properties of new compounds.
