Synthesis and characterization of some inorganic-organic cyclomatrix type tetrameric phosphazene polymers

Phosphazenes, due to their structural properties and different usage areas, have wide range of research possibilities in inorganic chemistry. Therefore, it is a rapidly developing subject in inorganic chemistry. The reticulated polyphosphazenes are cyclomatrix type polyphosphazene compounds that contain excess crosslinking. One of the cyclophosphazenes, octachlorocyclotetraphosphazene (tetramer) is of great importance as it is used as the main component of many phosphazene compounds. In this study, cyclomatrix type polyphosphazenes were synthesized in different types from the reaction of eight kinds of molar ratios using octopamine, 4,7-dihydroxy isoflavone (4,7-DHF), quercetin and isoprenaline monomers with cyclic linker phosphazene compound octachlorocyclotetraphosphaphene (tetramer). The characterizations of the synthesized cyclomatrix polyphosphazene nano/microspheres were performed using SEM, FT-IR, 31P-NMR and XRD techniques.
