The synthesis and characterization of some o-dianisidine and 3,3'-diaminobenzidine derived polyphosphazene micro/nano spheres

Polyphosphazenes can react with functional groups easily and by various methods to form compounds of different properties. Controlled drug release of polyphosphazenes, enzyme activities, surgical materials, hydrophobic-hydrophilic materials, technological products as liquid crystals, sensors, thermal resistant materials, ion transfer membranes, catalyst support etc. applications. Therefore, the fields of study are compounds that develop over time. In this study, the synthesis and structure of some polyphosphazene compounds derived from o-dianisidine and 3,3'-diaminobenzidine are aimed. According to the precipitation polymerization method, it was tried to obtain cyclomatrix polyphosphazene micro/nano spheres in different ratios from the reactions of o-dianisidine and 3,3'-diaminobenzidine monomers and trimer (N₃P₃Cl₆) and tetramer (N₄P₄Cl₈). Of these, microspheres were synthesized from the other experiments except o-dianisidine-trimer (reverse ratio) and 3,3'-diaminobenzidine-tetramer (straight ratio). The structures of the products were analyzed by SEM, FT-IR and XRD spectral methods and their characterizations were made.
