In this study, new cyclotriphosphazene derivatives bearing 2-naphthylthio group were reported. The reactions of hexachlorocyclotriphosphazene (1) with 2-naphthalenethiol (2) were carried out with NaH base in tetrahydrofuran solution under inert (Ar) atmosphere in (1:2), (1:4) and (1:6) molar ratios. As a result of the reactions, bis geminal (3), tetrakis (4) and hexakis (5) 2-naphthylthio substituted cyclotriphosphazene derivatives formed and isolated. These new compounds were characterized with elemental analysis, mass (MALDI-TOF) analysis, 31P{H} and 1H NMR spectroscopies. The molecular structure of compound 3 was illuminated by single-crystal X-Ray diffraction technique. Furthermore, the fluorescence properties of the newly designed and synthesis compounds (3-5) were examined.
