“…The literature contains reports on the synthesis of different linear, cyclic or poly phosphazenes [44][45][46][47][48][49][50][51][52][53][54][55][56][57]. There are limited reports (only three reports) in literature on the synthesis of phosphazenes containing chalcone derivatives [58][59][60].…”

The new hexasubstitue-cyclophosphazene compounds containing chalcone derivatives (2-11) were obtained from the reactions of hexachlorocyclotriphosphazene (1) with several hydroxy chalcones in K 2 CO 3 /acetone system. All products were generally obtained in high yields. The structures of the compounds were defined by elemental analysis, FT-IR, 1 H, 13 C and 31 P NMR spectroscopy. Dielectric measurements for phosphazenes containing chalcone compounds (5-8) were carried out by means of an impedance analyzer as a function of temperature and frequency. Dielectric properties of samples prepared in a plate form were measured at room temperature over the frequency range 50 Hz to 2 kHz and given as compared with each other.

“…The most well-known and studied derivatives of cyclophosphazenes are trimer (hexachlorocyclotriphosphazene) and tetramer (octachlorocyclotetraphosphazene). Thanks to their active phosphorus-chlorine bonds, they can be used with many different groups and easily give chlorine displacement reactions (10)(11)(12)(13)(14)(15)(16). Another reason these compounds are preferred is to be used as the starting material in the preparation of polyphosphazenes which is the largest class of known inorganic polymers (12).…”

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, 31 P{H} and 1 H 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.

“…In this research we study the cyclotriphosphazene compounds as a new photoconducting material. Although some novel cyclotriphosphazene structures and their physical properties have been reported [11][12][13][14], there is no study about the optoelectronic properties of the cyclotriphosphazene compounds bearing dioxyphenylcoumarin groups. The aim of this work is to determine how the photodiode prepared from both mono and di substituted dioxyphenylcoumarin bearing cyclotriphosphazene compounds (HCP-2 and HCP-4) change and how its characteristics alter regarding with the number of coumarin attachment.…”
