“…Due to the increasing demand for modern materials with improved performance, interest in organic–inorganic cyclic systems and polymers is growing. Among them, cyclic compounds containing phosphorus and nitrogen [ 1 , 2 , 3 , 4 , 5 ]; phosphorus and oxygen [ 6 ]; boron and oxygen [ 7 , 8 ]; nitrogen, oxygen, and silicon [ 9 ] atoms; nitrogen-containing heterocyclic compounds based on imidazole and guanidine [ 10 ], including proton sponges, linear siloxanes, and phosphazenes [ 11 , 12 , 13 ]; organotin polymers [ 14 ]; and copper-containing coordination polymers [ 15 ] should be noted. Researchers continue to find new applications for such compounds.…”

Condensation of hexakis-2-(formylphenoxy)cyclotriphosphazene with malonic acid yielded hexakis-2-(β-carboxyethenylphenoxy)cyclotriphosphazene (2-CEPP), whose structure was confirmed by 31P, 1H, 13C NMR spectroscopy and MALDI-TOF mass spectrometry. A quantum-chemical calculation for the 2-CEPP molecule using the ab initio methods in the 6-311G** basis set and the DFT-PBE0/6-311g** method was performed with geometry optimization of all parameters by the standard gradient method. The acid strength of 2-CEPP was theoretically estimated. Using the small-angle X-ray scattering method, it was found that 2-CEPP is an amorphous substance, which, when heated, can transform into a crystalline state. However, when heated at 370 °C, 2-CEPP undergoes decarboxylation and polymerization to form an insoluble heat-resistant product. The occurrence of decarboxylation and polymerization reactions in the formed styrene fragments was confirmed by thermal (differential-scanning calorimetry) and spectral (solid-state 13C NMR spectroscopy) analysis.

Phosphazenes are compounds containing the [P═N] motif. Three broad classes of compounds fall in this category: (a) acyclic phosphazenes, also known as iminophosphoranes, (b) cyclophosphazenes and (c) polyphosphazenes. There has been a growing tendency in the literature to bunch all polymeric compounds containing the phosphazene motif in the category of polyphosphazenes. While we would be dealing all polymeric compounds in the subsection on polyphosphazenes, the distinction between the various types needs to be appreciated. Polyphosphazenes are those that contain a [P═N] backbone with substituents on phosphorus. Other forms of polymers could be regarded as hybrid polymers which often contain an organic backbone with phosphazene pendant groups or cross-linked polymers containing interconnected cyclophosphazene units. This chapter summarizes the literature on phosphazenes that was published in the calendar year 2020.
