New cyclotriphosphazene derivatives featuring amide–Schiff base linkages with a hydrazine bridge and different terminal ends, such as decyl alkyl chains hydroxy groups, were successfully synthesized characterized. Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), CHN elemental analysis used to characterize the structures of these compounds. The formation hydrazine-bridged was confirmed by FTIR spectra, showing primary amine band for amide linkage around ~3300 cm−1 Schiff near ~1595 cm−1. This further supported NMR analysis, which displayed an proton (H-N-C=O) at ~δ 10.00 ppm azomethine (H-C=N) within δ 8.40–8.70 range. 31P spectra compounds display singlet 8.20 ppm, indicating upfield shift that suggests complete substitution all phosphorus atoms identical side chains. Furthermore, verified purity compounds, percentage error below 2%. introduction bridges into core significantly enriches molecular structure diverse functional groups. These modifications not only improve compound’s stability reactivity, but also expand its potential wide range applications.
